In previous grades, you used division to solve a variety of problems. Division is an operation that is used for grouping, partitioning, and other applications.

You have used division with several different types of numbers, including whole numbers, decimals, and fractions.

For whole numbers and decimals, you represented division with a number sentence or a division bracket. Each representation shows the relationship among the dividend, divisor, and quotient.
