set up a proportion first.
for this type of problem you write the proportion like this: x/10,000 = 6.13/100
So you won't forget, here's the formula: part/whole = percent/100
Now cross multiply: x/10,000 = 6.13/100
x*100 = 6.13 * 10,000
100x = 61300
Divide each side by 100
100x/100 = 61300/100
x = 613
So, 6.13% of $10,000 is $613.
The outcome is not always the percent without the decimal, but this one was because we were working with zeros.
