Question

Ginny’s favorite cookie recipe requires 1 1/2 cups of sugar to make 24 cookies. How much sugar does Ginny need to make 36 of these cookies?

Answer 1

Ginny needs $2\frac{1}{4}$ cups of sugar to make 36 cookies.

Step-by-step explanation:

Given,

Cups of sugar required to make 24 cookies = $1\frac{1}{2}=\frac{3}{2}\ cups$

Ratio of cups to cookies = $\frac{3}{2}:24$

Let,

x be the cups of sugar required to make 36 cookies

Ratio of cups to cookies = x:36

Using proportion;

Ratio of cups to cookies :: Ratio of cups to cookies

$\frac{3}{2}:24::x:36$

Product of mean = Product of extreme

$24*x=\frac{3}{2}*36\\24x=54$

Dividing both sides by 24

$\frac{24x}{24}=\frac{54}{24}\\x=\frac{9}{4}\\x=2\frac{1}{4}$

Ginny needs $2\frac{1}{4}$ cups of sugar to make 36 cookies.
