12 - (3^2 - 7) * 4 = 12 - (9 - 7) * 4 = 12 - 2 * 4 = 12 - 8 = 4

8/12 +7/12 =15/12 = 1 1/4
In the dataset {8, 0, 7, 7, 9, 12, 3, 7, 4, 6, 7, 8, 9, 6, 4} the 8 appears twice. → The frequency of the 8 is 2.
7/12+8/12 = 15/12 15/12 = 5/4 or 1.25
84 / 12 = seven ( 7 ) times
12 ÷ 8 = 1 remainder 4
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
It is 4 + 9 + 8 + 5 + 12 + 6 + 7 units.
7/12 + 8/12 = 15/12 = 1 and 3/12 = 1 and 1/4
4, 8, 12 and so on.
