It looks like you're adding two fractions: (13/6) and (7/8): 13/6+7/8....
First you need a common denominator between 6 and 8.
24 is the lowest common denominator.
Then multiply divide 24/6 = 4, and 24/8 = 3, so multiply (13/6)*(4/4) = 52/24, and (7/8)*(3/3) = 21/24.
Now with common denominators, you only need to add the numerators: 52 + 21 = 73. So the fraction 73/24 is the answer, as a mixed number : 3 1/24.
5/13 + 6/7 = 35/91 + 78/91 = 1 and 22/91
6 + (-13) =6 - 13 = -7
13/141/2 * 7/7 = 7/143/7 * 2/2 = 6/14===========...............13/14
It is: 7+13-6+5 = 19
6 + 13 + 2 + 12 + 7 + 14 = 54
13/42
The answer is 13/4 or 3.25 if you prefer decimals Math: 3/2 + 7/4 is the same as 6/4 + 7/4. 6 plus 7 equals 13 13/4
5/13 + 6/7 = 35/91 + 78/91 = 1 and 22/91
6 + (-13) =6 - 13 = -7
7
13/141/2 * 7/7 = 7/143/7 * 2/2 = 6/14===========...............13/14
(7+6)/32 = 13/9 or about 1.44444
1
6/7 * 6/13 = (6*6)/(7*13) = 36/91
It is: 7+13-6+5 = 19
6 + 13 + 2 + 12 + 7 + 14 = 54
13/9 or 1 4/9
