Answer:


1 (7)/(20)

Explanation:

Well you should find a common denominator for 10, 4 and 5 first to be able to mix them. Let's take 20 because it's the smallest number we can convert 10, and 4 and 5 to.

So


(3 * 2)/(10 * 2) + (1 * 5)/(4 * 5) + (4 * 4)/(5 * 4)

And you get

6/20 + 5/20 + 16/20 (now you can add them because they all have 20 as denominator) so = 27/20 = 1 7/20
