Question

Twenty students ride on your bus. Two fifths of them pack their lunches. How many of the students pack their lunches ?

Answer 1

Hi there!~

About 2 of them would pack their lunches, you would do "20 / 2/5"

Answer 2

If there are 20 students and 2/5 of them packed lunches you would do
2/5 x 25/25 which would equal 0.4
You would change 0.4 into a percent which would be 40%
40% of 20 = 8

Your answer would be 8 students
