Question

Xavier spent less than 2\5 of an hour walking home from school. Which fraction is less than 2\5? A5\7 B3\4 C5\10 D2\9

Answer 1

2/9 is less than 2/5 because since the denominator is larger, the pieces are smaller. (Numerator)

Answer 2

Answer: D. 2/9 - the reason I knew this was smaller was because the numerator(number in the top part of the fraction) stayed the same, but the denominator increased meaning we are dividing the same amount by a larger number of divisions. This means that it will be a smaller fraction.  


Why do none of the other answer choices fit? Well, either the numerator increased or both the numerator and denominator increased by a margin that made the final fraction larger than the original 2/5.

Any questions?
