What do order fractions mean?

Answer 1

Working left to right, like reading a sentence, you write the fractions from smallest to largest, thus putting them in order. If the directions say "largest to smallest", then you write them in that order.

For example, 1/4 is less than 1/2, 1/2 is less than 3/4 so the order would be (from smallest to largest)

1/4, 1/2, 3/4
