Exercise 11 Page 249

The percent equation is an equation in which the part is equal to the product of the corresponding percent and the whole. We can represent a is p percent of wwith the following equation. a= p% * wWe can find what percent of 72 is equal to 108 by substituting a= 108 and w= 72 into the formula and solve for p% using the Properties of Equality.

Since 1.5 equals 150%, we can complete percent equation. 108= 150% * 72 We found that 108 is 150 % of 72.
