Add. simplify the answer and write as a mixed number if appropriate 4/5+ 3/10+ 1/2 =

1 and 3/5

Step-by-step explanation: The common denominator is 10. So, in order for everything to have a denominator of 10, we need to multiply a few things.

4 x 2 = 8

5 x 2 = 10

1 x 5 = 5

2 x 5 = 10

With that out of the way, we can finally move on to figure out the answer.

8/10 + 3/10 + 5/10 = 16/10. The question asks to write as a mixed number, if necessary. And it is. So:

10 goes into 16 once, with 6 left over, so 1 and 6/10. the fraction can be reduced, so we do that. Because 2 goes into 6 (3 times), and 2 goes into 10 (5 times), that leaves us with a final answer of 1 and 3/5.
