Question 1129432
if x is 25% of y....
<pre>
Since 25% = 0.25 = {{{25/100}}},

and since "of" means "multiplied times"

{{{x = expr(25/100)y}}}

{{{x = expr(1/4)y}}}

{{{expr(1/4)y = x}}}

{{{4*expr(1/4)y = 4*x}}}

{{{1y = 4x}}}

{{{y = 4x}}}
</pre>
y is what percent of x?
<pre>
Since 4 = 4.00 = 400%

{{{y = "400%"x}}}

And since "multiplied times" means "of", then:

y is 400% of x.
