The expression is:
6/9 + 7/12
Note that 6/9 is evaluated to 2/3. Then we have:
2/3 + 7/12
Since the LCD is 12, multiply the top and bottom by 4 for 2/3 to get:
2/3 * 4/4 + 7/12
= 8/12 + 7/12
Finally...
8/12 + 7/12
= (8 + 7)/12
= 15 / 12
= 1 3/12
= 1 ¼
-7/12 + 10/12 = 3/12 = 1/4
6/12 + 8/12 = 6+8/12 = 14/12 = 7/6 = 11/6
The answer is 9 over 12 or 3 over 4
5/6
14 over 12, and/or 7 over 6, and/or 1 and 1 over 6
They add up to 7/6 or 1 and 1/6
7/12 - without using a calculator !
99 to 10
7/12 1/6 = 2/12 5/12 + 2/12 = 7/12
73/4 + 61/6 = 167/12 or 1311/12
719/24
It is 7/6 in its simplest form
