Tom painted 3/5 of his bedroom on monday and 1/10 of his bedroom on tuesday. how much does he have left to finish?

2/15

4/15

3/10

7/10

Tom has 3/10 of his room left to finish painting. The third choice is correct.

Explanation: Let’s write this as an equation.

Let x be the fraction of room that Tom has left to finish.

(3/5 + 1/10) + x = 1

Rewrite 3/5 as 6/10 so that it has a common denominator with 1/10.

(6/10 + 1/10) + x = 1

Combine like terms.

7/10 + x = 1

Subtract 7/10 from both sides.

x = 3/10

Therefore, since we know x = 3/10, we know that Tom has 3/10 of his room left to finish painting. The third choice is correct.
