How to calculate proportions
Sister Mouse's wedding was a big success, except for one thing: There wasn't enough rice! Big Brother Mouse, who was in charge of that department, didn't realize that if you have 50 times as many guests as usual, you need 50 times as much food.
So his friend, Little Elephant, teaches him how to calculate proportions. "Oh, my brain hurts!" exclaims the mouse, after his first lesson. But with continued practice, he soon masters a skill that is often useful for everyone - from mice who plan weddings, to doctors who have to adjust medicine dosages in proportion to a patient's weight.
