5th Grade Math Review Multiplication/Division

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times: 3 + 3 + 3 + 3 = 12.

Front

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 divided by 4 (12 ÷ 4) means splitting 12 into 4 equal parts, which equals 3.

How do you estimate the total cost of multiple items?

Back

To estimate the total cost, round the prices of each item to the nearest whole number, then multiply by the quantity of each item and add the results.

Front

What is a quotient?

Back

A quotient is the result of dividing one number by another. For example, in the division 20 ÷ 5, the quotient is 4.

Front

How do you find the total weight of multiple items?

Back

To find the total weight, multiply the weight of one item by the number of items. For example, if one mango weighs 7.4 ounces and there are 28 mangoes, the total weight is 7.4 x 28 = 207.2 ounces.

What is the formula to find the number of rows needed for seating?

Back

To find the number of rows needed, divide the total number of students by the number of seats per row. For example, 864 students with 54 seats per row means 864 ÷ 54 = 16 rows.

How do you calculate the weight of an adult animal based on its birth weight?

Back

To calculate the weight of an adult animal, multiply the birth weight by the growth factor. For example, if a lion cub weighs 3.6 pounds and grows to 99.9 times its birth weight, the adult weight is 3.6 x 99.9 = 359.64 pounds.

Front

What is rounding in mathematics?

Back

Rounding is the process of adjusting a number to make it simpler and easier to work with, usually to the nearest whole number or specified decimal place.

Front

What is the difference between an estimate and an exact answer?

Back

An estimate is a rough calculation or approximation, while an exact answer is the precise value obtained through calculation.

Front

What is repeated addition?

Back

Repeated addition is the process of adding the same number multiple times, which is the basis of multiplication. For example, 4 + 4 + 4 = 12 is the same as 3 x 4.
