what're you supposed to be doing?

Adding/subtracting fractions = common denominator and then from there you either add or subtract the numerators

Multiplying fractions = multiply the numerator times the numerator and denominator times denominator

Dividing fractions = reciprocal (aka flip) the second fraction then just multiply numerator times numerator and denominator times denominator.


Anything with prevents you can just move the decimal two places to the right so 5% is the same thing as .05 or if you want in fraction form then you just divide by 100 so 5% is also 5/100 is also .05

Easy stuff, u should do well 
 
You want a complicated word problem with percents and fractions then ....

A PIMD player makes "P" plunder every time he hits his farm and has a "Z" percent chance of winning. That player can increase his chance of winning by "T"% for every "W" he spends on items. He is weakened each time he attacks and makes "L"% less of his max plunder after each attack. He also has a "R"% less chance to win after each attack since he is being weakened. How much money should he spend on items for the Nth attack to maximize profit?
 
P can be any number I want to assign it to  but u can't choose it  and the answer has multiple variables and a lengthy fraction divided by a lengthy set of numbers 
