Answer:

See a solution process below:

Explanation:

"Percent" or "%" means "out of 100" or "per 100".

Therefore x% can be written as #x/100#.

We can now write this equation and solve for #x#:

#x/100 = 140/50#

#color(red)(100) xx x/100 = color(red)(100) xx 140/50#

#cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = cancel(color(red)(100))2 xx 140/color(red)(cancel(color(black)(50)))#

#x = 280#

140 is #color(red)(280%)# of #50#

Answer:

#280%#

Explanation:

The question is probably easier to read if it is given as:

What percent is #140" out of "50#?

To find what percent one value is of another, use the following:

#"fraction" xx 100%#

#140/50 xx10280%#

#=280%#

Note that multiplying by #100%# is the same as #xx 100/100# which is equal to #1#. This does not affect the value of the fraction, only what it looks like.
