The distance is (1.25-\left\(-2.75\right\)=4) units. In exams, do not miss signs while subtracting negative decimals.
Step 2
Why this answer is correct
The correct answer is B. (4) इकाई / (4) units. The distance is (1.25-\left\(-2.75\right\)=4) units. In exams, do not miss signs while subtracting negative decimals.
Step 3
Exam Tip
दूरी (1.25-\left\(-2.75\right\)=4) इकाई है। परीक्षा में ऋणात्मक दशमलव घटाते समय चिह्न न भूलें।
The distance is (\frac{5}{2}-\left\(-\frac{3}{2}\right\)=4) units. In exams, always take distance as positive.
Step 2
Why this answer is correct
The correct answer is C. (4) इकाई / (4) units. The distance is (\frac{5}{2}-\left\(-\frac{3}{2}\right\)=4) units. In exams, always take distance as positive.
Step 3
Exam Tip
दूरी (\frac{5}{2}-\left\(-\frac{3}{2}\right\)=4) इकाई है। परीक्षा में दूरी हमेशा धनात्मक लें।
A. (1) के बाद तीसरा निशान जब (8) बराबर भाग हों/Third mark after (1) when there are (8) equal parts
Step 1
Concept
\(1+\frac{3}{8}\) is the third of (8) equal parts after (1). In exams, count the fractional parts after the integer.
Step 2
Why this answer is correct
The correct answer is A. (1) के बाद तीसरा निशान जब (8) बराबर भाग हों / Third mark after (1) when there are (8) equal parts. \(1+\frac{3}{8}\) is the third of (8) equal parts after (1). In exams, count the fractional parts after the integer.
Step 3
Exam Tip
\(1+\frac{3}{8}\), (1) के बाद (8) बराबर भागों में तीसरे भाग पर है। परीक्षा में पूर्णांक के बाद भिन्न भाग गिनें।
The denominator of \(\frac{5}{6}\) is (6), so the segment from (0) to (1) has (6) equal parts. In exams, the denominator tells the number of parts.
Step 2
Why this answer is correct
The correct answer is B. (6) भाग / (6) parts. The denominator of \(\frac{5}{6}\) is (6), so the segment from (0) to (1) has (6) equal parts. In exams, the denominator tells the number of parts.
Step 3
Exam Tip
\(\frac{5}{6}\) में हर (6) है, इसलिए (0) से (1) तक (6) बराबर भाग होंगे। परीक्षा में हर भागों की संख्या बताता है।
\(-\frac{17}{5}=-3-\frac{2}{5}\), so it lies between (-4) and (-3). In exams, keep the sign of a negative mixed number correct.
Step 2
Why this answer is correct
The correct answer is B. \(-3-\frac{2}{5}\). \(-\frac{17}{5}=-3-\frac{2}{5}\), so it lies between (-4) and (-3). In exams, keep the sign of a negative mixed number correct.
Step 3
Exam Tip
\(-\frac{17}{5}=-3-\frac{2}{5}\), इसलिए यह (-4) और (-3) के बीच है। परीक्षा में ऋणात्मक मिश्र संख्या का चिह्न ठीक रखें।
\(\frac{13}{4}=3+\frac{1}{4}\), so it lies one-fourth after (3). In exams, convert an improper fraction into a mixed number.
Step 2
Why this answer is correct
The correct answer is A. \(3+\frac{1}{4}\). \(\frac{13}{4}=3+\frac{1}{4}\), so it lies one-fourth after (3). In exams, convert an improper fraction into a mixed number.
Step 3
Exam Tip
\(\frac{13}{4}=3+\frac{1}{4}\), इसलिए यह (3) के बाद एक चौथाई पर होगा। परीक्षा में विषम भिन्न को मिश्र संख्या में बदलें।
\(\sqrt{2}\) lies between (1) and (2), so \(5-\sqrt{2}\) lies between (3) and (4). In exams, change limits carefully while subtracting.
Step 2
Why this answer is correct
The correct answer is B. (3) और (4) / (3) and (4). \(\sqrt{2}\) lies between (1) and (2), so \(5-\sqrt{2}\) lies between (3) and (4). In exams, change limits carefully while subtracting.
Step 3
Exam Tip
\(\sqrt{2}\) (1) और (2) के बीच है, इसलिए \(5-\sqrt{2}\) (3) और (4) के बीच होगा। परीक्षा में घटाने पर सीमा सावधानी से बदलें।
\(\sqrt{3}\) lies between (1) and (2), so \(2+\sqrt{3}\) lies between (3) and (4). In exams, adding a number shifts the whole interval forward.
Step 2
Why this answer is correct
The correct answer is B. (3) और (4) / (3) and (4). \(\sqrt{3}\) lies between (1) and (2), so \(2+\sqrt{3}\) lies between (3) and (4). In exams, adding a number shifts the whole interval forward.
Step 3
Exam Tip
\(\sqrt{3}\) (1) और (2) के बीच है, इसलिए \(2+\sqrt{3}\) (3) और (4) के बीच होगा। परीक्षा में जोड़ने पर पूरा अंतराल आगे खिसकता है।
Since \(\sqrt{18}\) lies between (4) and (5), \(-\sqrt{18}\) lies between (-5) and (-4). In exams, the direction reverses for negative square roots.
Step 2
Why this answer is correct
The correct answer is C. (-5) और (-4) / (-5) and (-4). Since \(\sqrt{18}\) lies between (4) and (5), \(-\sqrt{18}\) lies between (-5) and (-4). In exams, the direction reverses for negative square roots.
Step 3
Exam Tip
क्योंकि \(\sqrt{18}\) (4) और (5) के बीच है, इसलिए \(-\sqrt{18}\) (-5) और (-4) के बीच होगा। परीक्षा में ऋणात्मक वर्गमूल में दिशा उलटी हो जाती है।
Since \(3^2=9\) and \(4^2=16\), \(\sqrt{10}\) lies between (3) and (4). In exams, bracket square roots between perfect squares.
Step 2
Why this answer is correct
The correct answer is B. (3) और (4) / (3) and (4). Since \(3^2=9\) and \(4^2=16\), \(\sqrt{10}\) lies between (3) and (4). In exams, bracket square roots between perfect squares.
Step 3
Exam Tip
क्योंकि \(3^2=9\) और \(4^2=16\), इसलिए \(\sqrt{10}\) (3) और (4) के बीच है। परीक्षा में वर्गमूल को पूर्ण वर्गों से घेरें।
Since \(3^2=9\) and \(4^2=16\), \(\sqrt{15}\) lies between (3) and (4). In exams, use nearby perfect squares to locate square roots.
Step 2
Why this answer is correct
The correct answer is B. (3) और (4) / (3) and (4). Since \(3^2=9\) and \(4^2=16\), \(\sqrt{15}\) lies between (3) and (4). In exams, use nearby perfect squares to locate square roots.
Step 3
Exam Tip
क्योंकि \(3^2=9\) और \(4^2=16\), इसलिए \(\sqrt{15}\) (3) और (4) के बीच है। परीक्षा में वर्गमूल की स्थिति के लिए नजदीकी पूर्ण वर्ग देखें।
Since \(\sqrt{12}>\sqrt{3}\), \(-\sqrt{3}\) is greater and lies to the right. In exams, negative signs reverse the comparison effect for square roots.
Step 2
Why this answer is correct
The correct answer is A. \(-\sqrt{3}\). Since \(\sqrt{12}>\sqrt{3}\), \(-\sqrt{3}\) is greater and lies to the right. In exams, negative signs reverse the comparison effect for square roots.
Step 3
Exam Tip
क्योंकि \(\sqrt{12}>\sqrt{3}\), इसलिए \(-\sqrt{3}\) बड़ा है और दाईं ओर होगा। परीक्षा में ऋणात्मक वर्गमूलों की तुलना करते समय चिह्न उल्टा प्रभाव देता है।
(-0.2) is negative and greater than (-1). In exams, place small negative decimals between (-1) and (0).
Step 2
Why this answer is correct
The correct answer is B. (-1) और (0) / (-1) and (0). (-0.2) is negative and greater than (-1). In exams, place small negative decimals between (-1) and (0).
Step 3
Exam Tip
(-0.2) ऋणात्मक है और (-1) से बड़ा है। परीक्षा में छोटे ऋणात्मक दशमलव को (-1) और (0) के बीच रखें।
Numbers decrease to the left on the number line, and (2.9<3). In exams, connect the left direction with the smaller number.
Step 2
Why this answer is correct
The correct answer is D. (2.9). Numbers decrease to the left on the number line, and (2.9<3). In exams, connect the left direction with the smaller number.
Step 3
Exam Tip
संख्या रेखा पर बाईं ओर संख्या छोटी होती है और (2.9<3) है। परीक्षा में बाईं दिशा को छोटी संख्या से जोड़ें।
Numbers increase to the right on the number line, and (-1>-2). In exams, connect the right direction with the greater number.
Step 2
Why this answer is correct
The correct answer is C. (-1). Numbers increase to the right on the number line, and (-1>-2). In exams, connect the right direction with the greater number.
Step 3
Exam Tip
संख्या रेखा पर दाईं ओर संख्या बड़ी होती है और (-1>-2) है। परीक्षा में दाईं दिशा को बड़ी संख्या से जोड़ें।
\(\frac{5}{4}=1+\frac{1}{4}\), so it is one-fourth after (1). In exams, convert an improper fraction into mixed form.
Step 2
Why this answer is correct
The correct answer is A. \(1+\frac{1}{4}\). \(\frac{5}{4}=1+\frac{1}{4}\), so it is one-fourth after (1). In exams, convert an improper fraction into mixed form.
Step 3
Exam Tip
\(\frac{5}{4}=1+\frac{1}{4}\), इसलिए यह (1) के बाद एक चौथाई भाग पर है। परीक्षा में अपूर्ण भिन्न को मिश्र रूप में बदलें।
The opposite point of (-7) is (7) because both are equally distant from (0). In exams, change the sign to identify the opposite number.
Step 2
Why this answer is correct
The correct answer is A. (7). The opposite point of (-7) is (7) because both are equally distant from (0). In exams, change the sign to identify the opposite number.
Step 3
Exam Tip
(-7) का विपरीत बिंदु (7) है क्योंकि दोनों (0) से समान दूरी पर हैं। परीक्षा में विपरीत संख्या पहचानने के लिए चिह्न बदलें।
