Problem 7: Multiply and reduce the answer.

Answer. Multiply the numerators and multiply the denominators, but leave them in factored form .

Then reduce the fraction by factoring the numerator and the denominator and located the fraction within the mix that has a value of 1. The fraction can be written as

This can be reduced further to

The fraction cannot be reduced further because the numerator and denominator do not share any common factors. Therefore the answer is

By now you know how to check the answer with your calculator. Calculate140 divided by 260 and 3000 divided by 310 and multiply the answers. Now calculate 2100 divided by 403. If the answers are the same, you have successfully worked this problem.
