What is the solution to the proportion?

4/12=10/x

x = 3
x = 3.3
x = 4.8
x = 30

4/12=10/x

Cross multiply and solve for x.

4x = 120

x = 120/4

x = ?

30?

4/12=10/x 4x/4=120/4 x=30

thanks

To find the solution to the proportion 4/12 = 10/x, you can use cross multiplication. Cross multiplication is a method used to solve proportions.

First, multiply the numerator of the left fraction (4) with the denominator of the right fraction (x), and multiply the denominator of the left fraction (12) with the numerator of the right fraction (10).

So, the equation becomes: 4 * x = 12 * 10.

Simplifying the equation gives:
4x = 120.

To solve for x, divide both sides of the equation by 4:
x = 120 / 4.

Which gives:
x = 30.

Therefore, the solution to the proportion is x = 30.
