Question

If 120% of a is equal to 80% of b, then what is the value of a b in terms of b

Answer 1

120% = x 1.2

80% = x 0.8


`1.2a=0.8b \\ \\ a= (0.8)/(1.2)b \\ \\ \boxed{a= (2)/(3)b }`

Answer 2

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.
