Question

The number $75$ is decreased by $40\%$, then the result is again decreased by $40\%$. What is the final result?

Answer 1

To get 75 decreased by 40% you subtract 40% from 100%.
100 - 40 = 60

So to get 60% of 75 you multiply .60 by 75.
.60 x 75 = 45

You have $45 now, but you have to decrease it by 40% again. You do the same process, so we need to multiply .60 by 45.
.60 x 45 = 27

So, the final result is $27.
