Question

A school-bus is dropping students off after school. When the bus left the

school, there were 40 students on the bus, and now there are 16. What is the
percent decrease from the start of the ride to now?

Answer 1

Answer: 60% decrease

40 - 16 = 24

24/40 = 0.6 = 60%

Answer 2

60%

Explanation:

40-16=24

24/40=0.6

0.6*100=60

First, work out the difference (decrease) between the two numbers you are comparing.

Decrease = Original Number - New Number

Next, divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100
