Question

What percent of 520 is 52

Answer 1

We can answer that in several ways.

If 52 is the 100%, then 520 is ten times that, which is 10*100%, therefore, 520 is 1000% of 52

We also can use a rule of three, simple, direct proportion to solve it:
52  ------> 100%
520 -----> x

x = (520)(100)/52
x = 1000
therefore 520 is the 1000% of 52

Answer 2

That would be ,10%. Work : 52/520 = .1 which in percent form is 10%.
