Question

A cookie recipe uses 1/2 teaspoon of vanilla with 3/4 cup of flour. How much vanilla should be used with five cups of flour?

Answer 1

we are given

A cookie recipe uses 1/2 teaspoon of vanilla with 3/4 cup of flour

so,

$\frac{3}{4} flour=\frac{1}{2}vanilla$

we can find for 1 cup of flour

so, we will multiply both sides by 4/3

$\frac{4}{3}\times \frac{3}{4} flour=\frac{4}{3}\times \frac{1}{2}vanilla$

$1 flour=\frac{2}{3}vanilla$

now, we can find for 5 cup of flour

so, we will multiply both sides by 5

and we get

$5\times 1 flour=5\times\frac{2}{3}vanilla$

$5 flour=\frac{10}{3}vanilla$...............Answer
