You can check by using your estimated number and comparing it with your exact quotient.
To check if a division answer is correct, you can multiply the quotient (the result of the division) by the divisor (the number you divided by). If the product equals the original dividend (the number being divided), then the division answer is correct. Additionally, you can estimate by rounding the numbers to see if the quotient falls within a reasonable range.
Estimate the answer. If the calculated answer is close to the estimate then it is reasonable.
12 centimetres is a reasonable estimate.
To use multiplication to check the quotient, you multiply the quotient by the divisor given! For instance: 6 / 2 = 3 Then, to check that 3 is the quotient of 6 and 2, multiply 3 by 2 to get 3 x 2 = 6.
24 is a reasonable estimate. (78% of 31 is 24.18).

12 centimetres is a reasonable estimate.
For multiplication or division, the only reasonable estimate is -2.
quotient is the answer to a division problem so after dividing, to check your answer, you need to take the quotient and multiply it to one of the given numbers.
To use multiplication to check the quotient, you multiply the quotient by the divisor given! For instance: 6 / 2 = 3 Then, to check that 3 is the quotient of 6 and 2, multiply 3 by 2 to get 3 x 2 = 6.
A more reasonable estimate would be 15.
A reasonable estimate is 1000. The actual total is 1016.
