5/12 - 4/12 = 1/12
It is: 7/12
1 whole and 7 over 12
19/21 - 4/12 (4/12 = 1/3) = 12/21Convert the 1/3 into 7/21 and subtract.
to subtract (or add) fractions you need tohave a common denominator 7/12 - 1/3 = 7/12 - 4/12 = 3/12 = 1/4
5/12 - 4/12 = 1/12
11/12 subtract 1/3=
It is: 7/12
change 1/4 to twelfths = 3/12. Now you can subtract: 7/12 - 3/12 = 4/12, which simplifies to 1/3.

19/21 - 4/12 (4/12 = 1/3) = 12/21Convert the 1/3 into 7/21 and subtract.
to subtract (or add) fractions you need tohave a common denominator 7/12 - 1/3 = 7/12 - 4/12 = 3/12 = 1/4
First, you have to make the denominators the same. 7 4 --- - --- 12 12 Then, you subtract. 7 4 3 1 --- - --- = --- = --- 12 12 12 4
The problem is 1/3 - 1/12. To work out the problem, the denominators must be the same. 1/3 needs to be changed to 4/12 in order to subtract 1/12. So, 4/12 - 1/12 = 3/12 which is the same as 1/4.
If you take 12 and subtract 1/4, the answer is 11 3/4. A 1/4 is equal to .25.
3/4 minus 1/6 is 7/12
13/20 - 3/5 = 13/20 - 12/20 = 1/20
