Question

To make coffee,the ratio of teaspoons of creamer to teaspoons of sugar is 4 to 5. If I use 10 teaspoons of creamer, how many teaspoons of sugar do I need?

Answer 1

Answer:

8 teaspoons of sugar

Step-by-step explanation:

Make a proportion

You use 4 teaspoons of sugar for 5 teaspoons of creamer, and x teaspoons of sugar for 10 teaspoons of creamer

4/5=x/10

Cross multiply

5*x=4*10

5x=40

Divide both sides by 5 to isolate x

x=8

So, for 10 teaspoons of creamer, you will use 8 teaspoons of sugar
