**Models** can be used to find the quotient of a decimal and a whole number.

In a 10 by 10 grid, an entire row or column represents 0.1,

and one square represents 0.01.

In a 1 by 10 grid, each section represents 0.1.

Each small square represents 0.01, or one hundredth, so 2.48, or

248 hundredths, can be represented by shading 248 of the small squares.

Divide the squares into 8 equal groups.

Each group has 31 squares, which represents 31 hundredths, or 0.31.

So, 2.48 ÷ 7 = 0.31.

First, represent 3.2 on the number line.

Then, divide the space between 0 and 3.2 on the number line into 4 equal sections.

Each section is 0.8 unit long. So, 3.2 ÷ 4 = 0.8.
