Division is the process of splitting a number into equal parts. It answers the question of how many times one number is contained within another.

Solving a word problem involves reading a scenario, identifying the mathematical operations needed, and finding the solution.

To find the number of groups, divide the total amount by the size of each group.

The formula for division is: Total ÷ Group Size = Number of Groups.

A remainder is the amount left over after division when the numbers do not divide evenly.

To estimate, round the numbers to the nearest ten or hundred and then divide.

Multiplication and division are inverse operations; if a × b = c, then c ÷ b = a.

'About' indicates that the answer is an estimate, not an exact number.

You can check your division answer by multiplying the quotient by the divisor and adding the remainder, if any.

Units help clarify what is being measured or counted, ensuring the answer is meaningful.
