3 over 4= 0.75 1 over 5= 0.20 Subtract and you get: 0.55, or 11 over 20.

change 1/4 to twelfths = 3/12. Now you can subtract: 7/12 - 3/12 = 4/12, which simplifies to 1/3.
If you take 12 and subtract 1/4, the answer is 11 3/4. A 1/4 is equal to .25.
Because 3 is greater than 1. I suppose it's possible to do it in your head, if you remember that in the world of fourths, 1 - 3 equals 2 but it's easier to subtract 3/4 from 17/4 or 3 and 5/4. As long as you can get to 3 and 1/2, it doesn't really matter, but don't tell your teacher I said that.
Because you cannot subtract 3/4 from 1/4.
19/21 - 4/12 (4/12 = 1/3) = 12/21Convert the 1/3 into 7/21 and subtract.
7/8 - 6/8 = 1/8
