120% = x 1.2

80% = x 0.8

[tex]1.2a=0.8b \\ \\ a= \frac{0.8}{1.2}b \\ \\ \boxed{a= \frac{2}{3}b }[/tex]

If you would like to know what is the value of a b in terms of b, you can calculate this using the following steps:

120% of a = 80% of b
120/100 * a = 80/100 * b     /*100
120 * a = 80 * b     /120
a = 80 / 120 * b
a = 2/3 * b

The correct result would be a = 2/3 * b.
