TJ has 12 problems left on his math test. He has solved 2/3 of problems already. How many problems has TJ solved already?
A 36 problems
B 24 problems
C 48 problems
D 12 problems
TJ has solved 2/3 of the problems already. To find the number of problems he has solved already, multiply the total number of problems by the fraction of problems solved: 12 problems * 2/3 = <<12*2/3=8>>8 problems. Answer: \boxed{8}.
To solve this problem, we need to find 2/3 of 12.
Step 1: Multiply 12 by 2.
12 * 2 = 24.
Step 2: Divide the result by 3.
24 / 3 = 8.
Therefore, TJ has solved 8 problems already.
The correct answer is B) 24 problems.
To find out how many problems TJ has solved already, we need to calculate 2/3 of the total number of problems.
First, multiply the total number of problems (12) by 2/3:
2/3 * 12 = (2 * 12) / 3 = 24 / 3 = 8
So, TJ has solved 8 problems already.
Therefore, the answer is:
B) 24 problems.
