Um can someone me with this can't remember how to and too lazy to google it

15/9 x 9

The way I would do it, is to turn 9 in to 9/1; it is a lot easier to visualise multiplying fractions this way, if you're just starting off.

15/9 x 9/1

We multiply the numerators, and multiply the denominators, to give us one fraction.

(15 x 9)/(9 x 1)

135/9

This division can actually be performed without the use of decimal numbers, so 135 divided by 9 is 15.
