Mental Math Questions and Answers
- 1.
It is always less than the divisor.
- A.
Dividend
- B.
Remainder
Correct Answer
B. RemainderExplanation
The remainder is always less than the divisor because it represents the amount left over after dividing the dividend by the divisor. In division, the divisor is the number by which the dividend is divided, and the remainder is the amount that is left over. Since the remainder is the part that is not evenly divisible by the divisor, it will always be smaller than the divisor itself.Rate this question:

The words "rows of" mean...
- A.
Multiplication
- B.
Division
Correct Answer
A. MultiplicationExplanation
The words "rows of" indicate a multiplication operation. Multiplication involves combining equal groups or quantities, and the term "rows of" suggests that there are multiple sets or groups being multiplied together. In multiplication, the number of rows represents the number of groups or sets, and the number of items in each row represents the quantity in each group. Therefore, the correct answer is multiplication.Rate this question:

What is the estimated quotient of 560 by 11?
- A.
58
- B.
50
Correct Answer
B. 50Explanation
The estimated quotient of 560 divided by 11 is approximately 50.
To estimate this, you can round 560 down to the nearest multiple of 11, which is 550. Then, divide 550 by 11, and you get 50. This is a rough approximation, and the exact quotient is 560 divided by 11 equals 50.909090... (repeating).Rate this question:

What is the estimated product of 4,857 and 23?
- A.
10,000
- B.
100,000
Correct Answer
B. 100,000Explanation
The estimated product of 4,857 and 23 is 100,000. This is because when estimating the product, we round the numbers to the nearest ten or hundred and then multiply them. In this case, rounding 4,857 to the nearest thousand gives us 5,000, and rounding 23 to the nearest ten gives us 20. Multiplying 5,000 and 20 gives us 100,000, which is the estimated product.Rate this question:

- A.
47.4 - 14.5
- B.
47.7 - 15.9
Correct Answer
B. 47.7 - 15.9Explanation
The given question asks for the option with the least difference. To find the difference, we subtract the smaller number from the larger one. In the first option, the difference is 32.9, while in the second option, the difference is 31.8. Therefore, the second option (47.7 - 15.9) has the least difference.Rate this question:

Paul and Liza went shopping. They spent a total of 6,475 pesos. If Liza spent 1,895 pesos, how much did Paul spend shopping?
- A.
4,580 pesos
- B.
5,000 pesos
Correct Answer

It is the process of putting together sets of the same number.
- A.
Division
- B.
Multiplication
Correct Answer
B. MultiplicationExplanation
Multiplication is the correct answer because it involves the process of combining sets of the same number. In multiplication, you are essentially adding the same number repeatedly, which can be thought of as putting together sets of the same number. Division, on the other hand, involves splitting a number into equal parts, which is not the same as putting together sets of the same number.Rate this question:

The product of two numbers is 100. Their difference is 15. What are the two numbers?
- A.
25 and 10
- B.
20 and 5
Correct Answer
B. 20 and 5Explanation
The question states that the product of two numbers is 100 and their difference is 15. To find the two numbers, we need to find two numbers whose product is 100 and whose difference is 15. The only pair of numbers that satisfies these conditions is 20 and 5. The product of 20 and 5 is 100, and their difference is 15. Therefore, the two numbers are 20 and 5.Rate this question:

Which statement is TRUE?
- A.
Multiplication is the inverse of division.
- B.
Subtraction is the inverse of multiplication.
Correct Answer
A. Multiplication is the inverse of division.Explanation
In mathematics, the inverse of an operation "undoes" the effects of that operation. Multiplication and division are inverse operations of each other. If you multiply a number by another number and then divide the result by the same number, you get back to the original number. This relationship makes multiplication the inverse of division.Rate this question:
