I guess you mean how much is 7/8 of 2/3. If that is what you mean than the answer is: 7/8 * 2/3 = 14/24 = 7/12If you meant 7/8 : 2/3 it is: 7/8 : 2/3 = 7/8 * 3/2 = 21/16 (or 1 and 5/6) If you meanrt 7/8 + 2/3 it is: 7/8 + 2/3 = 21/24 + 16/24 = 37/24 (or 1 and 13/24)If you meant 7/8 - 2/3, it is : 21/24 - 16/24 = 5/24
