Question

A recipe calls for 2 cups of flour to make 15 biscuits how many cups of flour do u need to make 25 biscuits

Answer 1

You need $3\frac{1}{3}$ cups of flour to make 25 biscuits.

Step-by-step explanation:

Given,

Cups used to make 15 biscuits = 2 cups of flour

Ratio of cups to flour = 2:15

Let,

x be the number of cups needed to make 25 cups.

Ratio of cups to flour = x:25

Using proportion;

Ratio of cups to flour :: Ratio of cups to flour

$2:15::x:25$

Product of mean = Product of extreme

$15*x=25*2\\15x=50$

Dividing both sides by 15

$\frac{15x}{15}=\frac{50}{15}\\\\x=\frac{10}{3}\\\\x=3\frac{1}{3}$

You need $3\frac{1}{3}$ cups of flour to make 25 biscuits.
