Question

Bailey needed to make 32 biscuits. She has 4/16 cups of flour and that makes enough for 28 biscuits. How much more flour Does she need.

A.) 7/0
B.) 8/20
C.) 16/32
D.) none of the above

Answer 1

3/28 more cups of flour

Explanation:

For 28 biscuits = 4/16 cups

For 1 biscuit = 4/(16 x 28)

For 32 biscuits = 4/(16 x 28) x 32

= 4/448 x 32

= 4/14

= 2/7 cups

More flour required = 4/16 - 2/7

= 56/224 - 32/224

= 24/224

= 12/112

= 6/56

= 3/28 cups
