Question

8 1/2 divided by 2 1/4

Answer 1

3 7/9

Explanation:

a division of fractions can be solved in 2 ways :

1 .

a/b / c/d = a×d / b×c

2.

a/b / c/d = a/b × d/c = a×d / b×c

but first we need to bring these mixed numbers to full fractions.

8 1/2 = 16/2 + 1/2 = 17/2

2 1/4 = 8/4 + 1/4 = 9/4

and now

17/2 / 9/4 = 17×4 / 9×2 = 68/18 = 34/9

3×9 = 27, so 34/9 = 27/9 + 7/9 = 3 7/9

Answer 2

3/9 or 3 7/9
