The first step for simplifying the above fraction is to divide the terms with the same base by subtracting their exponents.

(15)/(18y^(-3-(-7)) )
Remember that when there is a "-" sign in front of the parenthesis,, we need to change the sign of each term in the parenthesis. This changes the fraction to the following:

(15)/(18y^(-3+7 ) )
Calculate the sum of the exponents.

(15)/(18 y^(4) )
Lastly,, reduce the fraction with 3 to find your final answer.

(5)/(6 y^(4) )
Let me know if you have any further questions.
