Shade the grid to show the fraction of the kids at summer camp that are taking an archery class.

What percent of the kids at summer camp are taking an archery class? You can use your model to help.

The grid has 100 squares.

You can find the number of kids that each square represents. The whole grid represents all 120 kids. Since the grid has 100 squares, you can divide.

120

100

1.2

Each square represents 1.2 kids.

48 of the kids are taking an archery class. Find the number of squares that represent 48 kids.

1.2

40 squares of the grid represent 48 kids. Shade 40 squares.

A percent tells you a part out of 100. 40 out of the 100 squares, or

40%

of the squares, are shaded. So,

40%

of the kids at summer camp are taking an archery class.
