Now we can solve our equation for x. 10 = 80x original equation. 10 80 = 80x 80 divide both sides by 80. 1 8 = x reduce: 10 80 = 1 8. 0.125 = x divide: 1 8 = 0.125. but we must express our answer as a percent. to do this, move the decimal two places to the right and append a percent symbol. John zimmerman, algebratesthelper explains how to solve percent problems using an equation; in this lesson, students learn to find a percent o.

Problems involving percents have any three quantities to work with: the percent, the amount, and the base. the percent has the percent symbol (%) or the word “percent.” in the problem above, 15% is the percent off the purchase price. the base is the whole amount. in the problem above, the whole price of the guitar is $220, which is the base. Percent problems percent problems – example 1: \(2.5\) is what percent of \(20\)? solution: in this problem, we are looking for the percent. use the following equation: \(\color{blue}{percent} = \color{ black }{part} \ ÷\) base \(→\) percent \(=2.5 \ ÷ \ 20=0.125=12.5\%\) the absolute best books to ace pre algebra to algebra ii.
