matthew got 36 problems right out of a total of 40 problems on a test. What percent of the problems did he get right?

(36/40) * 100 = ?

To find the percentage of problems Matthew got right, you need to divide the number of problems he got right by the total number of problems and then multiply by 100.

So, in this case, Matthew got 36 problems right out of a total of 40 problems.
To find the percentage:

Step 1: Divide the number of problems Matthew got right by the total number of problems:
36 / 40 = 0.9

Step 2: Multiply the result by 100 to find the percentage:
0.9 * 100 = 90

Therefore, Matthew got 90% of the problems right on the test.
