Question

in the past year tom watched 4 movies that he thought were very good. he watched 40 movies over the whole year. Of the movies he watched, what percentage did he rate as very good?

Answer 1

4/40 = 1/10 = 10%
So he rated 10% of movies as very good

Answer 2

10% of the movies, because 100/40 is 2.5 so you would do 4 x 2.5 which equals 10. AKA
So if you’re trying to change it to x/100, you would do cross division and get 10/100 which equals 10%
