How do you divide a fraction by a fraction?<br> 20 points!!

Hi!

When we divide a fraction for a fraction we have to multiply the first fraction for the opposite of the second (the one we're dividing for).

Let's do an example.

16/8 : 4/6 = 16/8 * 6/4

Where necessary you can do cross-semplifying.

So, 16 and 4 can be divided both for 4.

8 and 6 both for 2.

So we have 4/4*3/1

You can also semplify numerator and denominator...

4/4 = 1

1*3 = 3
