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

Answer:

$1\frac{2}{3}\ slabs$

Step-by-step explanation:

Let

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

y ----> the number of  cups of butter

we know that

The ratio is

$\frac{x}{y} =\frac{1}{1}$

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

$y=1\frac{2}{3}\ cups$

Remember that

$x=y$

so

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

therefore

$x=1\frac{2}{3}\ slabs$
