8 = .40(x)
8(10/4) = .40x(10/4)
80/4 = x
20 = x
x is 20, but you REALLY should start doing your homework and paying attention in class. Learning is important.

the percent of a number is when you multiply the percentage by the number, for example: 8% of 40 40 x 0.08= 20% or 20% of 40 0.20 x 40=8%
Saying that 24 is 60% of x is the same as saying: 24 = 60/100 ⋅ x So simply solve for x: ∴ 24 = 3x / 5 ∴ 8 = x / 5 ∴ x = 40
40 x .20 = 8 So 8 is your answer.
Is it 15 over 40?
75 percent is equal to 0.75, so the expression would look like (0.75x) +8. But if you do not know what it equals to it is not an equation and you can not solve it.
