10/13.

To get an equivalent expression, we multiply the numerator and denominator

by the same number.

In this case, our denominator went from 13 to 39. 39 / 13 = 3. So we multiplied our denominator by 3. So, we

must multiply our numerator by 3 also.

Our equivalent fraction is 30/39. We

know this is correct, because when we

DIVIDE the numerator and denominator by 3 we get 10/13 ,our original fraction.
