9-6 = 3 21-13= 8 8x3 = 24
21 - 13 = 8... 9 - 6 = 3... 8 x 3 = 24
21/24 - 8/24 = 13/24
13 + 26 + 34 + 21 + 38 + 42 = 174/6 = 29
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.
15+6 is 21. 13 + what is 21? 21 - 13 is 8 Eight
7/8 - 2/6 = 7/8 - 1/3 = 21/24 - 8/24 = 13/24
13 + 9 + (6/3) = 24
5/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/245/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/245/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/245/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/24
7/24 * 6/21 = 1/12
Multiplying top and bottom by 4, 5/6 = 20/24 Now we can compare. 21/24 is greater than 20/24, therefore 21/24 is greater than 5/6
The Least Common Multiple (LCM) of 6, 13, and 24 is 312.
