How do you set up a proportion to find 16 percent of 90?
use the rule: is / of = percent / 100reword the question in your head What is 16 percent of 90?(percent = 16) (of = 90) is is the unknown pick a variable -- xx / 90 = 16 / 100 now solve for xx = 14.4
Why should you use percent equation rather than the percent proportion?
There is no "should" or "should not". The depends on the question that you are trying to answer.
How do you find the percent proportion?
A simple tool to remember is: IS over OF equals percent over 100.If we put this into a proportion, we get:IS/OF = percent/100.Just put all percent problems into this format, and solve the proportion.Example: 12.5 IS what percent OF 75?Or,12.5 IS | what percent | OF 75?Just put these numbers into the proportion: (We will use x for the percent, as that is the unknown we are solving for)12.5/75 = x/100.Then solve by cross multiplying:75x = 1250.Then divide by 75:x = 1250/75,x = 16 2/3 %
What is a situation in which you would have to use a proportion?
To find a percent.
