Answer: x = 52

Step-by-step explanation: Well percent means over 100 so we know that 25% means 25/100. Of means times, what number means x, is means equals, and 12 means 12. So we can translate this problem into an equation.

So we have the equation 25/100 · X = 13

Notice that 25/100 can be reduced to 1/4.

So rewriting our problem we have X/4 = 13.

To get rid of the fraction, we multiply both sides of the equation by 4 and we have x = 52.

This means that 25% of 52 is 13.
