Explanation of Solution
Given:
Expression:
Concept used:
To multiply two fractions, simply multiply numerators by each other and denominators by each other and then reduce the fraction if possible.
To divide two fractions, simply flip the second fraction into a reciprocal and change the division sign to a multiplication sign and then multiply the two fractions by multiplying the numerators by each other and denominators by each other. As illustrated below:
Calculation:
Consider the given expression,
Conclusion:
Therefore, after simplification, the answer is
