Answer:
B
Step-by-step explanation:
To find a certain percentage of a number, we need to get the decimal equivalent of the percentage and then multiply this with the number.
For our problem given, we need to multiply 72 with the decimal equivalent of 310%.
How do we convert percentage to decimal?
We divide by 100. So we have:
310% = 310/100 = 3.1
Now, we multiply:
3.1 * 72
We don't need to do this as the question simple asks for the expression. Hence looking a the answer choices, We can say B is the correct answer.
