Question

How do you divide `\frac { \frac { 7} { 9x - 8} } { \frac { x } { 3x + 4} }`?

Answer 1

`= (7(3x+4))/(x(9x-8)) =(21x+28)/(9x^2-8x)`

Explanation:

You can write this as a division rather than as a fraction.

`7/(9x-8) div x/(3x+4)`

`= 7/(9x-8) xx (3x+4)/x`

`= (7(3x+4))/(x(9x-8)) =(21x+28)/(9x^2-8x)`

This does not simplify further,

You can leave it in factor form or multiply the brackets.
