Solve the proportion for x: 1/3 = x/12

Answer 1

To find the value of x, we first find the fraction that is equivalent to 1/3 that has a denominator of 12.

Multiplying or dividing the numerator and denominator of

a fraction by the same number will give us an equivalent fraction.

So if we multiply both the numerator and denominator of

the first fraction by 4, we can see that 1/3 = 4/12.

So the value of x must be 4.

Answer 2

Method #1:

Starting with the proportion, cross multiply

3x = 1(12)

3x = 12

x = 12/3

x = 4

Method 2:

Starting with the proportion, determine what number multiplies with 3 to get 12 (that would be 4) and multiply the top number (1) by 4 as well to get x equal to 4.

Answer 3

1/3 = x/12

1 = x/4

x = 4
