Answer explanation

10 squares are shaded in the model. There are 100 total squares in the model. The fraction of the model shaded is 10/100. 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. 10/100 = 10%.
