Question

What percent of 850 is 531?

Answer 1

$\frac{531}{850} \times 100 = 62.5$
62.5%

Answer 2

850 is 100%, so 532 is x% — this is a ratio:

850:100% = 532:x% — inverse multiplication (inner with inner, outer with outer)

x% * 850 = 100% * 532 — divide the whole eqtn with 850 to isolate x%

x% = (100% * 532) / 850
x% = 53200% / 850
x% = 62.5% (roughly)
