To check your division, use multiplication. This is a fundamental method taught even around the 5th grade. Here's how it works:
-
Identify the Quotient, Divisor, and Dividend: Understand the parts of a division problem. For instance, in the problem 32 ÷ 2 = 16:
- 32 is the Dividend (the number being divided).
- 2 is the Divisor (the number you are dividing by).
- 16 is the Quotient (the result of the division).
-
Multiply the Quotient by the Divisor: Multiply the quotient you obtained by the divisor you used.
-
Compare to the Dividend: The result of this multiplication should equal the dividend.
Here's a simple table to illustrate this:
Operation | Dividend | Divisor | Quotient |
---|---|---|---|
Division | 32 | 2 | 16 |
Check | |||
Multiplication | 2 | x 16 | |
Result | 32 |
Example:
As given in the reference:
- 32 ÷ 2 = 16
Check:
- Multiply the divisor (2) by the quotient (16): 2 x 16 = 32.
- Since 32 (the result of the multiplication) is equal to the dividend (32), your division is correct.
This method provides a straightforward way to verify the accuracy of your division calculations.
