When we multiply algebraic fractions, we try to reduce or cancel down any top term with a bottom term that has a common factor.
We look for any top term which has a common factor with any bottom term.
If we find such a pair of terms, we divide them by their common factor.
|=||a3 ÷ a2||x||5|
|10||7a2 ÷ a2|
|=||a||x||5 ÷ 5|
|10 ÷ 5||7|
Let's try some questions now.
