Here, operate with similar terms together, 
so, 24/56 = 12/28 = 6/14 = 3/7

Now, with x-coefficient: x⁶⁻⁴ = x²  [ Subtract exponent of denominator from numerator ]

with y-coefficient: y³⁻⁷ = y⁻⁴ = 1/y⁴

Now, Merge your all results: 3x² / 7y⁴

In short, Your Final Answer would be: 3x² / 7y⁴

Hope this helps!
