If m>0 and x is m percent of y, then, in terms of m, y is what percent of x?
x=my/100
y=?/100*x
We want the answer in terms of m. So, from x=my/100, we can solve for m. After we do this, we get:
m=100x/y
We want ?/100 in terms of m. From y=?x/100, ?=100y/x.
100y/x= 10000/m E

A. 100m
B. (1/100m)
C. (1/m)
D. (10/m)
E. (10000/m)
x= m/100*y

y= 100/m *x

y is (100/m)/100 % of x
--> 1/m %

C

Given x/y = m%=m/100

Obviously y/x = 100/m = 10000/m %
