Question

The sum of 1/9, 2/3, and 5/18is A. 8/30. B. 12/9. C. 19/18. D. 4/15.

Answer 1

The least common multiple of 9, 3, and 18 is 18.

Convert 1/9 to 2/18.

Convert 2/3 to 12/18.

Then add the numerators:

2 + 12 + 5 = 19

So the answer is 19/18, or 1 1/18 if you prefer.

Answer 2

First I would add 1/9+2/3=7/9
next i would add 7/9+5/18= 1 1/18
