1/5     =.    3/ 15 because you are multiplying the numerator by 3 so the denominator has to be multiplied by 3 as well

7/8    =.     14/16 because you are multiplying the numerator by 2 the denominator has to be multiplied by 2 as well

1/6.   =.   2/12 because you are multiplying the numerator by 2
