A recipe for 6 dozen cookies colls for 3/4 cup of sugar. How much sugar is needed for 4 dozen cookies?

Answer 1

This is a proportion question. If we change 3/4 to 0.75, it will look better on wyzant. x represents the amount of sugar we'll need.

0.75/6 = x/4

We can use cross multiplication to rewrite this:

0.75*4= 6*x

Simplify the left side:

3= 6*x

Then divide both sides by six to isolate the x:

3/6 = x

Simplify:

0.5 = x or, 1/2 a cup.
