42 % = 42 / 100
40 = x * 42 / 100 Multiply both sides by 100
40 * 100 = 42 x
4000 = 42 x Divide both sides by 42
4000 / 42 = x
x = 95.238
OR
42 % = 42 / 100 = 0.42
x = 40 / 0.42 = 95.238
40 = x * 42 / 100 Multiply both sides by 100
40 * 100 = 42 x
4000 = 42 x Divide both sides by 42
4000 / 42 = x
x = 95.238
OR
42 % = 42 / 100 = 0.42
x = 40 / 0.42 = 95.238
