3/4 minus 1/6 is 7/12
to subtract (or add) fractions you need tohave a common denominator 7/12 - 1/3 = 7/12 - 4/12 = 3/12 = 1/4
6/7 - 2/3 = 18/21 - 14/21 = 4/21
19/21 - 4/12 (4/12 = 1/3) = 12/21Convert the 1/3 into 7/21 and subtract.
Subtract 7/24 from 4/8 to get 5/244/8 * 3/3 = 12/2412/24 -5/24 = 7/24
