Question

How do you solve `(5x)/7=8/9`?

Answer 1

`x = 56/45`

Explanation:

If an equation has ONLY one term on each side and at least one is a fraction, you can get rid of the fractions by cross-multiplying.

`(5x)/7=8/9`

`5x xx9 = 7xx 8`

`5x = 56/9`

`x = 56/(9xx5) = 56/45`

This does not simplify and a fraction answer is better than decimal which would recur.
