Question

Isaac used 1/4 of an ounce of nuts to make 1/12 pound of cake. How many ounces of nuts are needed to make a cake?

Answer 1

`frac{1/4"oz nuts"}{1/12" cake"}=frac{x" oz nuts"}{1 " cake"}`

Multiply the left side by `12/12`:
`frac{3"oz nuts"}{1 " cake"}=frac{x" oz nuts"}{1 " cake"}`

`x=3" oz nuts"`
