[(unknown number ) x 79 ] / 100 = 395
unknown number = [ 395 x 100] / 79
unknown number = 39500 / 79 = 500
then 395 is the 79% of 500

x being the number we are looking for
79%=.79 a number we can work with
395/.79=x/1 1 represents 100% (99%=.99) so it would follow
that100% would be 1
x=395/.79=500
lets do a check and lets see if 21% of 500 =105
.21*500=105
105+395=500
Anwsar395 is 79% of 500

79% = 0.79
395 is 79% of what number translates into math as
0.79*x = 395
so
x = 395/0.79 = 500

Assume this un known number is X.
Therefore, 79/100*X=395,
You get 79X=39500, Or X=500

Let it be y
Then,
79% of y= 395
79/100 x y= 395
y= 395 x 100/79
y= 500
500 is the required number.

.79 ( x) = 395 divide both sides by .79
(x) = 500

There's an easy logical question to ask urself when stuck on problems like that:
if 395 is 79% of the number, then how much is 100% of it?
then turn this question into an equation:
395 ---- 79/100
? ---- 100/100
then : (395 x 1) / 0.79 (that's called the scissors method)
the answer is 500
