Question

A biscuit recipe calls for 3 2/3 cups of flour for 1 batch. How many cups are needed for 3 1/4 batches?

Answer 1

This problem can be solved easily using a proportion:

`3(2)/(3) - 1`

`x - 3(1)/(4)`

So,
`x= (3(2)/(3) * 3(1)/(4))/(1)=3(2)/(3) * 3(1)/(4)=(11)/(3) * (13)/(4)=(11*13)/(3*4)=(143)/(12)=11(11)/(12)`

The answer:
`11(11)/(12)` cups are needed.

Answer 2

Multiply 3.6666 by 3.25 to get 11.9167 cups.
