Exercise 19 Page 251

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 300 is equal to 51 by substituting a= 51 and w= 300 into the formula and solve for p% using the Properties of Equality.

Since 0.17 equals 17%, we can complete percent equation. 51= 17% * 300 We found that 51 is 17 % of 300.
