What is the inverse operation for multiplication?
- A.
Addition
- B.
Subtraction
- C.
Division
Correct Answer
C. DivisionExplanation
The inverse operation for multiplication is division. When we multiply two numbers together, we can use division to undo or reverse the operation and find one of the original numbers. Division involves splitting a number into equal parts or groups, which is the opposite of combining or multiplying numbers together. Therefore, division is the correct answer as it undoes the effect of multiplication.Rate this question:

Correct Answer
C. MultiplicationExplanation
The inverse operation for division is multiplication. This is because division undoes the effect of multiplication. When we divide a number by another number, we are essentially finding out how many times the second number can fit into the first number. Multiplication, on the other hand, is the process of adding a number to itself a certain number of times. So, if we multiply the quotient obtained from division by the divisor, we get back the original dividend, which shows that multiplication is the inverse operation for division.Rate this question:

Correct Answer
A. AdditionExplanation
The inverse operation for subtraction is addition. This is because addition and subtraction are opposite operations. When you subtract a number from another number, you can use addition to reverse the process and get back to the original number. For example, if you subtract 5 from 10, you get 5. To reverse this and get back to 10, you can add 5. Therefore, addition is the inverse operation for subtraction.Rate this question:
