the answer is c.
you need to find the least common denominator. in this case, its 24. therefore 2/3 becomes 16/24 (you multiply both top and bottom by 8, since 3*8=24), 3/8 becomes 9/24 (multiply top and bottom by 3), and 5/12 becomes 10/24 (multiply top and bottom by 2)
so your new equation is 16/24+9/24+10/24...which when added = 35/24. 35 goes into 24 once with 11 remaining. therefore your answer is 1 11/24.
hope that helped. :)

Multiplying 2/3 with 8 u got: 16/24
Multiplying 3/8 with 3 u got: 9/24
Multiplying 5/12 with 2 u got: 10/24
Then add those three:16/24+9/24+10/24=35/24=24/24+11/24=1 and 11/24
So the correct answer is C

To start try finding the greatest common factor they all share, which would be 24.
Then make them all numbers with a denominator of 24.
Then numbers would then be made:
2/3=16/24
3/8=9/24
5/12=10/24
(The numbers aren't in lowest terms so you will have to add the numerators then make them to lowest terms)
16/24+9/24+15/24=35/24
Then think "How many times does 35 go into 24?"
The answer would be 1 remainder 11
That would be written: 1 11/24
You already know 1 is in lowest terms,so you then have to figure out "Is 11/24 in lowest terms?"
You find out if a numbers in lowest terms by finding the Least Common Factor.
The factors of 11 are: 1,11
The Factors of 24 are:1,24,2,12,3,8,4,6
The least common factors both numbers have our 1.
So you then know you can't divide the problems by any number but one to get you to lowest terms.
The answer would then be C.,1 and 11/24
Hope I made it easy enough to understand!

2/3 = 16/24
3/8 = 9/24
5/12 = 10/24
16+9+10 = 35
35/24 = 1 11/12
So, the answer is C

35/24 == 1 and 11 / 24
its gonna be:
16/24 + 9/24 + 10/24 = 35/24

C. is the correct answer Because when u find the common denominatorand the times the topby thwaht you had to times the bottom by and then add
