Question

A batch of chicken required 3 1/3 cups of flour if a fast food restaurant was making 4 3/7 batches, how much flour would they need ?

Answer 1

3 1/3 x 4 3/7

= 10/3 x 31/7 = 310/21 = 14 16/21

Answer 2

`14(16)/(21)` cups of flour

Explanation:

1 batch of chicken required 3 1/3 cups of flour

`3(1)/(3) =(3 \cdot 3 + 1)/(3) =(10)/(3)`

the fast food restaurant was making 4 3/7 batches.

We need to find how much of flour they need to make 4 3/7 batches

`4(3)/(7) =(4 \cdot 7 + 3)/(7) =(31)/(7)`

1 batch requires
`(10)/(3)` cups of flour

`(31)/(7)` batches requires
`(31)/(7) \cdot (10)/(3)`

`(310)/(21)=14(16)/(21)`
