Subtract show all of your work 7/8 - 1/6

First of all, the denominators are not the same. To fix this, simply multiply the two denominators together.

Now we have x/48 - y/48 = ?

How many times does 8 go into 48? 6 times. 6 times the numerator which is 7

How many times does 6 go into 58? 8 times. 8 times the numerator which is 1

Now we have 42/48 - 8/48 = 34/48

Can we simplify 34/48? Yes.

34/48 / 2/2 = 17/24

7/8 = 42/48

1/6=8/48

Your answer would be 34/48 or 7/8
