Question

mercurys radius is 2440, and jupiturs radius is 71,492. Mercurys radius is what percent of jupiturs radius?

Answer 1

2440 is what percent of 71,492

percent formula : is/of = %/100

is = 2440
of = 71492
% = x

now we sub
2440/71492 = x/100
cross multiply because this is a proportion
(71492)(x) = (2440)(100)
71492x = 244000
x = 244000 / 71492
x = 3.413%
