Among the proper fractions with 18 ad the denominator, which of them are larger than 1/2 but smaller than 5/6?

Answer 1

A proper fraction has numerator less than denominator.

Mark numerator less as x.

You can write this question as:

1 / 2 < x / 18 < 5 / 6

Multiply both sides by 18

1 / 2 ∙ 18 < x < 5 ∙ 18 / 6

9 < x < 15

Your proper fractions are:

10 / 18

11 / 18

12 / 18

13 / 18

14 / 18
