3.9 is 10% of 390

"Percent" or "%" means "out of 100" or "per 100", Therefore 10% can be written as #10/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for #n#:

#n = 10/100 xx 39#

#n = 390/100#

#n = 3.9#
