What is the correct increasing order of 0.09, 0.9, and 0.19 on the number line?
Answer and explanation
Correct answer: 0.09, 0.19, 0.9
Write the decimals with equal place values: 0.09, 0.19, and 0.90. Comparing the hundredths and tenths places gives 9 < 19 < 90, so the increasing order is 0.09 < 0.19 < 0.9. Option D is incorrect because 0.9 is greater than 0.19, not smaller. Exam tip: Add trailing zeroes when needed so that decimals have the same number of places before comparing them.
