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 %

How can you use the percent proportion to solve real world problems?
The percent proportion can be used to solve real-world problems by setting up a ratio that compares a part to the whole, expressed as a percentage. For example, if you want to find out what percentage of a class passed an exam, you can set up the equation ( \frac{\text{part}}{\text{whole}} = \frac{\text{percent}}{100} ). This allows you to easily calculate unknown values, such as the percentage of sales tax on an item or the proportion of a budget allocated to different expenses. By applying this formula, you can make informed decisions based on quantitative data.

Why can you solve percent problems as a proportion problem?
Because you simply set it up in a proportion box, for example if you have the fraction 4/8 you put the 4 on top of the 8 and 100 next to the 8 because with percents you always use 100. then solve,
