Let's flip the second fraction to get a multiplication exercise:
We'll combine the fractions into one exercise:
Let's factor 36 into a smaller multiplication exercise:
We'll reduce the 12 in both the numerator and denominator of the fraction:
\( 100-(5+55)= \)
Dividing by a fraction is the same as multiplying by its reciprocal. When you see , it becomes !
Treat variables just like numbers! When multiplying, add the exponents: m × m = . When canceling, variables in numerator and denominator can cancel out.
Yes, absolutely! Look for common factors you can cancel first. In this problem, the 12 in the numerator cancels with part of 36 in the denominator, making the math easier.
That's perfectly normal! Many fraction problems result in variables in the denominator. Just make sure your final answer is fully simplified and matches the form given in the answer choices.
Check your factoring: 36 = 12 × 3. You can verify by multiplying back: 12 × 3 = 36 ✓. This helps you see which factors can cancel with other parts of the fraction.
