Question

Rebecca's teacher wrote the division problem on the board. Using the vocabulary box, label the parts of the division problem. Then, using the vocabulary, explain how Rebecca can check whether her teacher's whole-number quotient is correct.

Vocabulary:

Whole-number quotient
Scale
Divisor
Dividend
Remainder

Answer 1

Step-by-step explanation:

The result should be equal to the original dividend. In this case, 25=25

25=25, so the calculation is correct.

Therefore, Rebecca can check the correctness of her teacher's whole-number quotient by verifying that when the divisor is multiplied by the quotient and the remainder is added, it equals the original dividend. If the equality holds, the division problem is correct.

Answer 2

The parts of a division problem are dividend, divisor, quotient, and remainder. To check the correctness of the whole-number quotient, multiply the divisor by the quotient and add the remainder to see if it equals the dividend.

Step-by-step explanation:

In a division problem, there are four main parts: dividend, divisor, quotient, and remainder.

1. The dividend is the number being divided.
2. The divisor is the number by which you are dividing.
3. The quotient is the whole-number result of the division.
4. The remainder is the amount left over after dividing.

To check whether the teacher's whole-number quotient is correct, Rebecca can multiply the divisor by the quotient and add the remainder. If the product plus the remainder equals the dividend, then the quotient is correct.
