ok . I am trying to make all the denominator common ie 20

so for $\displaystyle \frac{16}{5}$ , in order to make its denominator 20 ,

i will need to take 5 and multiply by 4 , when i multiply the denominator by 4 , i will need to multiply the numerator by 4 as well - Sep 18th 2009, 07:55 AMandyboy179
