4 is what % of 20?

Answer 1

Hazel Anglin

4 is 20% of 20.

Let's first refer to the percentage of people searching for "p".

"Percent" or "%" means "out of 100" or "per 100", Therefore p% can be written as #p/100#.

The word "of" in relation to percents signifies "times" or "to multiply".

Putting this altogether we can write this equation and solve for #p# while keeping the equation balanced:

#p/100 xx 20 = 4#

#color(red)(100)/color(blue)(20) xx p/100 xx 20 = color(red)(100)/color(blue)(20) xx 4#

#cancel(color(red)(100))/cancel(color(blue)(20)) xx p/color(red)(cancel(color(black)(100))) xx color(blue)(cancel(color(black)(20))) = 400/color(blue)(20)#

#p = 20#
