F.Y.I.
To find the percent one number is of
another, use this proportion:
%
is
=
100
of
Because you are looking for 45% of 420,
45 replaces the percent sign and 420
replaces “of.” The first denominator, 100,
always stays the same. The “is” part is
what you have been asked to find.
Instead of using proportions, you
can also multiply to find a percent
of a number.
