Question

If each slab of butter is one cup, and you want to double a recipe that calls for 1 and 2/3 cups of butter, how many slabs of butter will you need?

Answer 1

`1(2)/(3)\ slabs`

Explanation:

Let

x -----> the number of slabs of butter

y ----> the number of cups of butter

we know that

The ratio is

`(x)/(y) =(1)/(1)`

so

`x=y`

That means-----> The number of slabs of butter must be equal to the number of cups of butter

In this problem

we have

`y=1(2)/(3)\ cups`

Remember that

`x=y`

so

The number of slabs of butter needed must be equal to the number of cups of butter

therefore

`x=1(2)/(3)\ slabs`
