x/(100+x)×100 = 20
x/(100+x) = 20/100
x/(100+x) = 2/10
10x = 200+2x
10x-2x = 200
8x = 200
x = 200/8
x = 25

x/(100+x) × 100 = 20
x/(100+x) = 20/100
x/(100+x) = 1/5
Cross multiplication,
5x = 100+x
5x-x = 100
4x = 100
x = 100/4
x = 25
x/(100+x) = 20/100
x/(100+x) = 1/5
Cross multiplication,
5x = 100+x
5x-x = 100
4x = 100
x = 100/4
x = 25
