Percent Modeling

What percentage of the model is shaded?

• 75%

• 55%

• 25%

• 15%

Answer explanation

25 squares are shaded in the model. There are 100 total squares in the model. The fraction of the model shaded is 25/100. A percent, or percentage, is a special fraction that always has 100 as the denominator. Because the bottom of a percent is always 100, we don’t even write it. We remove the 100 and put a % instead. 25/100 = 25%.

• 40%

Answer explanation

40 squares are shaded in the model. There are 100 total squares in the model. The fraction of the model shaded is 40/100.
