6/7 - 2/7 = 4/7
4/7 minus 1/6 = 17/42
It is: 7/12
7/8 - 6/8 = 1/8
you need to equal them out, so it is actually 48 over 56 (times by 8) subtract 7 over 56 (times by 7). so the answer is 41 over 56.
8 1/6 - 2 5/6 = 5 1/3. Here's how I did it. Borrow a 1 from the 8 and change it to 6/6 & add to 1/6, so you have 7 and 7/6. Subtract 5/6 from 7/6 = 2/6, which equals 1/3. Subtract 2 from 7 = 5.

6/7 - 2/3 = 18/21 - 14/21 = 4/21
7/8 - 2/6 = 7/8 - 1/3 = 21/24 - 8/24 = 13/24
3/4 minus 1/6 is 7/12
To subtract ninths from sixths, you have to first convert them both to 54ths. So, 7/9 x 6/6 = 42/54 and 5/6 x 9/9 = 45/54. Now you can do the subtraction. 45 - 42 = 3. So the answer is 3/54.
7 times 6 is 42. If you subtract two, you get 42-2= 40.
