7/15 / (3/5)

Flip the 2nd fraction and multiply:

7/15 * 5/3

Multiply the numerators and denominators together:

35/45

Divide 5 to the numerator and denominator:

35 / 5 = 7
45 / 5 = 9

7/9
you would flip 7/15 to its reciprocal to get 15/7 and multiply it by 3/5 
to get 45/35 and if you simplify it you will get 9/7 as your answer
