One Restaurant uses 5 quarts of soup to make 20 equal servings. Another restaurant uses 7 quarts of soup to make 25 equal servings.which restaurant has larger servings of soup?

Question

i don't understand what to do and how to do this

Answer 1

2nd restaurant gives larger servings

5/20 for first per serving = 25/100 quarts per serving

2nd restaurant has 7/25 = 28/100 quarts per serving

28/100 > 25/100

28>25

7/25 > 5/20
