Question

Solve the proportional equation
5/12 = x/15

Answer 1

x=6.25

Explanation:

Cross multiply

5/12=x/15

12*x=15*5

12x=75

Divide both sides by 12 to isolate the variable x

x=6.25

Or, multiply both sides by 15 to "reverse" the division being done to x

5/12=x/15

15*5/12=x/15*15

6.25=x

Answer 2

Answer: 6.25.

Explanation:

Let's put your question into a proper proportional form, because it is a ratio that is equal.

`(5)/(12) = (x)/(15)`

To solve proportions, you have to cross-multiply in the direction that has numbers, which is 5 and 15, then divide to 12.

`5 * 15 / 12 = 6.25`

The answer you should get by doing this is 6.25.
