Answer:
3/10
Step-by-step explanation:
3/5 + 1/10
3/5 = 6/10
6/10 + 1/10 = 7/10 = total bedroom space he painted
10/10 - 7/10 = 3/10 = how much space is left
Answer = 3/10
Answer: 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.
