Question

A muffin recipe calls for 3/4

cup of sugar for every 1/2
teaspoon of salt. How much salt should be used for every 1 cup of sugar?
A. 3/8 teaspoon
B. 2/3 teaspoon
C. 3/4 teaspoon
D. 1 teaspoon

Answer 1

Answer: B (2/3 tsp)

Explanation:

Set equal to each other to look for x.

3/4 cups sugar per 1/2tsp salt is (3/4)/(1/2) and we are looking for 1 cup sugar. Therefore:

`(3/4)/(1/2) = 1/x`

Cross multiply. You should get:

`1/2=3/4x`

Divide both sides by 3/4.

`(1/2)/(3/4)=x\\(1/2)*(4/3)=x\\4/6=x`

Simplify

x=2/3

So you will use 2/3 tsp salt for every 1 cup sugar.
