100
There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.
It really depends on the specific problem; but quite often, there are several ways to solve such problems.
The rules for solving word problems are read the problem, decide what you need to do, solve the problem, and check your answer.
Please give a sample problem.
100
A percent is simply a proportion out of 100.
Hit the "e" key before the "r" key when typing percent. That should solve the problem.
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 %
That would depend on the specific problem. The "rule of three" (i.e., solving proportions) can help for many standard problems; i.e., you consider a proportion, where the percentage has a denominator of 100. Here are some examples:1) What's 17% of 2000? The proportion to solve is: 17/100 = x/2000 2) 500 is what percentage of 2000? The proportion to solve is: x/100 = 500/2000 3) 500 is 10% of what number? The proportion to solve is: 500/x = 10/100
Part = Base*Percent/100Proportion = Part/Base = (Base*Percent/100)*Base = Percent/100.
72 To solve, set up 63/x=.875 and solve for x.
what problem did the hershey solve
Set up a proportion equation.
they are mathmatical problem u mulitlpy nd then add then subtract
It really depends on the problem
Historians solve many different problems; there is no "key problem"
