2 2/3 +4 1/8 =

Answer 1

6 19/24

Explanation:

1. Find the LCM(lowest common multiple) of 3 and 8 which is 24
2. Multiply the denominator of 2/3 by 8 and 1/8 by 3
3. Whatever you do to the denominator you have to do to the numerator, so you also have to multiply the numerator of 2/3 by 8 and 1/8 by 3 = 2 16/24 + 4 3/24
4. Add the whole numbers (4+2= 6)
5. Add the fractions (16/24 + 3/24= 19)
6. Put them together and the answer is 6 19/24
