To find the percent of problems Martin has left to do, we need to find the number of problems he has left to do.
Out of 10 math problems, Martin has answered 7 of them. So, he has 10 - 7 = 3 problems left to do.
To find the percent, we need to calculate the ratio of the number of problems Martin has left to do (3) to the total number of problems (10) and then multiply by 100.
(3/10) x 100% = 30%
Therefore, Martin has 30% of the problems left to do.
