Natalie prepared 36 kilograms of dough after working 4 hours. How many hours did Natalie work if she prepared 45 kilograms of dough?

Answer 1

We can set up a proportion based on the relationship between the amount of dough prepared and the time worked.

Given: Natalie prepared 36 kilograms of dough in 4 hours.

Find: How many hours it would take to prepare 45 kilograms of dough.

So, if x is the number of hours it takes to prepare 45 kilograms, then:

36kg/4hours = 45kg/x

To solve for x, we start by cross multiply:

36 kg • x hours = 45 kg • 4 hours

36x = 180 , divide both sides by 36

x = 5.

Therefore, Natalie worked for 5 hours.
