### QUESTION 1 of 10

When we multiply algebraic fractions, we try to reduce or cancel down any top term with a bottom term that has a common factor.

Example

Simplify:

 a3 x 5 10 7a2

We look for any top term which has a common factor with any bottom term.

If we find such a reduceable pair of terms, we divide them by their common factor.

 a3 x 5 10 7a2

 = a3 ÷ a2 x 5 10 7a2 ÷ a2

 = a x 5 10 7

 = a x 5 ÷ 5 10 ÷ 5 7

 = a x 1 2 7

 = a 14
