Question

A batch of cookies calls for 3/4 cup of flour. You want to make 1/2 of a batch. How much flour do you need?

Answer 1

Answer

3/8 of cup

Explanation

To solve this we are going to use a proportion. We know that to make 1 batch of cookies we need 3/4 cup of flour, so to make 1/2 batch of cookies we'll need x cups of flour. In other words:

$\frac{1batch----->\frac{3}{4}cup.flour}{\frac{1}{2}batch----->xcup.flour}$

Now, we can express our proportion as a fraction and solve for $x$:

$\frac{1}{\frac{1}{2} } =\frac{\frac{3}{4} }{x}$

$x=(\frac{3}{4} )(\frac{1}{2} )$

$x=\frac{3}{8}$

You will need  3/8 of cup flour to make 1/2 of a bath of cookies.

Answer 2

We need 3/8 cup of flour to make half of the batch of cookies.
