Question

For every two students in a class who eats a hot lunch at school, three other students purchase from the a la carte line and 1 other student packs a lunch. If there were 25 students in class one day, how many students would you expect to order a hot meal

Answer 1

The ratio is 2:3 so... the total of them is 5

25/5=5  Therefore we can multiply 5x2  and 5x3

The new ratio is 10:15

Since the ratio is hot lunch:a la carte, The 10 is the amount of hot lunches expected and 15 is amount of students expected to eat a la carte

So 10 students eat hot lunch

15 students eat a la carte
