Hello!

First you have to make the denominators the same.

1/5 * 2 = 2/10

3/5 = 6/10

Then you add all the values together

2 2/10 + 3 6/10 + 4 1/10 = 9 9/10

Since our answer is not that close to 9 the students answer is unreasonable

Since 9 9/10 is close to 10 the answer is C

the answer is C

Hope this helps!
