When you multiply a fraction, you are dividing by the denominator. You do not need to change anything to divide.

For example:

12 x 5/6

This is saying, take 12 and multiply by 5 and divide it by 6.

and in

3/4 x 5/6

You are saying, multiply 3 and 5 then divide by 4 and 6. When you divide by a 4 and by a 6 are are actually dividing by the product of 4 and 6. So, all you have to do is multiply the numerators then multiply the denominators and do any reducing if needed.

So,

3/4 x 5/6 = 15/24 = 5/8
