Answer:
45% decrease
Step-by-step explanation:
The formula for percent of decrease/ increase is
Original - change/ original
So 40 - 22 = 18
18/40 = 0.45
Turn 0.45 to percent by moving the decimal two spaces to the right
45%
You can check by multiplying the original number by the percentage. So,
40 x 0.45 = 18
