1 1/2  3 2/5 + 8/15  2 2/3
You need to find the lowest common denominator for these fractions. Then perform the indicated arithmetic. What do you think the answer is?
(4 7/12)  (3 2/3) 1/24 + 2 5/8
(4 14/24)  (3 16/24)  1/24 + 2 15/24) =
4 14/24 + 3 16/24  1/24 + 2 15/24 =
 4 15/24 + 5 31/24 = 1 16/24 = 1 2/3
3 1/2  ( 1 5/6) + (1 1/12)+ 2 3/4
Your turn. What do you think the answer is?
810+(3)
2+(3)=5 is that the rite answer
Yes. That's the right answer.
2 7/9/ (1 4/81) 11/17
Try 1377 as the common denominator.
