It is always less than the divisor.
Correct Answer
B. Remainder
Explanation
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.
2.
The words "rows of" mean...
Correct Answer
A. Multiplication
Explanation
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.

What is the estimated quotient of 560 by 11?
Correct Answer
B. 50
Explanation
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).

What is the estimated product of 4,857 and 23?
Correct Answer
B. 100,000
Explanation
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.
5.
Which has the least difference?
Correct Answer
B. 47.7 - 15.9
Explanation
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.
6.
Which multiplication is less than 2,210?
Correct Answer
A. 32 x 65
Explanation
To determine which multiplication is less than 2,210, let's calculate both:
32×65=2,080
30×81=2,430
Therefore, 32×6532×65 is less than 2,210, making it the answer.
7.
What is the greatest remainder if the divisor is 7?
Correct Answer
A. 6
Explanation
The greatest remainder that can be obtained when dividing any number by 7 is 6. This means that when any number is divided by 7, the remainder will never be greater than 6.
8.
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?
Correct Answer
A. 4,580 pesos
Explanation
Since Liza spent 1,895 pesos and the total amount spent by both Paul and Liza is 6,475 pesos, we can subtract Liza's amount from the total to find out how much Paul spent. Therefore, Paul spent 6,475 - 1,895 = 4,580 pesos.
9.
It is the process of taking away.
Correct Answer
B. Subtraction
Explanation
Subtraction is the correct answer because it is the process of taking away. In mathematics, subtraction is an arithmetic operation that involves subtracting one number from another to find the difference between them. It is the opposite of addition and is used to find the result when something is removed or taken away from a given quantity. Therefore, subtraction fits the description of the process of taking away.
10.
It is the process of putting together sets of the same number.
Correct Answer
B. Multiplication
Explanation
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.
11.
8 x 7 =
Correct Answer
B. 56
Explanation
The expression 8Ã—7 represents the multiplication of the numbers 8 and 7. When you multiply them together, you get the product:
8Ã—7=56
So, the correct answer is 56.
12.
72 divided by 9 is
Correct Answer
B. 8
Explanation
The correct answer is 8 because when you divide 72 by 9, you are essentially asking how many times 9 can go into 72. Since 9 can go into 72 exactly 8 times (9 x 8 = 72), the answer is 8.
13.
The product of two numbers is 100. Their difference is 15. What are the two numbers?
Correct Answer
B. 20 and 5
Explanation
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.
14.
Which statement is TRUE?
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.
15.
55 x 6 =
Correct Answer
A. 330
Explanation
The correct answer is 330 because when you multiply 55 by 6, you are essentially adding 55 to itself 6 times. So, 55 + 55 + 55 + 55 + 55 + 55 equals 330.
16.
6 x 65 =
Correct Answer
A. 390
Explanation
The correct answer is 390 because when you multiply 6 by 65, you get the product of 390.
17.
240 divided by 6 is
Correct Answer
B. 40
Explanation
To find the result of dividing 240 by 6, we need to divide 240 by 6. When we do this calculation, we get the result of 40. Therefore, the correct answer is 40.

23 x 8 =
Correct Answer
B. 184
Explanation
The correct answer is 184 because when you multiply 23 by 8, you get the product of 184.
