Use muliplying by 1 to find an expression equivalent to 10/13 with a dominator of 39a
Please kindly help. I don't understand what to do. Thanks!
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.
