Exercise 3 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 600 is equal to 3 by substituting a= 3 and w= 600 into the formula and solve for p% using the Properties of Equality.

Since 0.005 equals 0.5%, we can complete percent proportion. 3= 0.5% * 600 We found that 3 is 0.5 % of 600.
