Question

Solve the following proportions: solve for x:
4/15=x/45

Answer 1

x=12

Explanation:

First, you'll have to cross multiply.

4/15=x/45

4(45)=x(15)

180=15x

Next, you'll want to flip the equation.

15x=180

Finally, you'll want to divide both sides by 15.

15x/15=180/15

x=12

Answer 2

x=4x3 so x=12 just multiply both digits on left with 3
