यदि (R) संख्या रेखा पर \(\frac{7}{2}\) पर है और (S), (R) से (2.25) इकाई बाईं ओर है, तो (S) का निर्देशांक क्या है?
If (R) is at \(\frac{7}{2}\) on the number line and (S) is (2.25) units to the left of (R), what is the coordinate of (S)?
Explanation opens after your attempt
A. \(\frac{5}{4}\)
Concept
\(\frac{7}{2}=3.5\) and \(3.5-2.25=1.25=\frac{5}{4}\). In exams, subtract the distance when moving left.
Why this answer is correct
The correct answer is A. \(\frac{5}{4}\). \(\frac{7}{2}=3.5\) and \(3.5-2.25=1.25=\frac{5}{4}\). In exams, subtract the distance when moving left.
Exam Tip
\(\frac{7}{2}=3.5\) और \(3.5-2.25=1.25=\frac{5}{4}\)। परीक्षा में बाईं ओर जाने पर दूरी घटाएं।
