1. James and four friends make 5 people total. Each has 1/5 of a bag, so 5 × (1/5) = 1 bag total.
2. Moses eats 2/3 of a sushi roll per day for 3 days: 3 × (2/3) = 2 sushi rolls total.
3. Rick has 8 bottles each 3/4 full: 8 × (3/4) = 6 full bottles’ worth of ketchup. He can fill 6 glass bottles completely.
4. 15 people each eat 3/16 of a pizza: 15 × (3/16) = 45/16 = 2 13/16 pizzas. Since you can’t serve a fraction of a pizza in practice, 3 pizzas are needed to feed everyone.
5. Jeanie needs 1/4 bag of cocoa powder per dozen cupcakes. For 10 dozen: 10 × (1/4) = 10/4 = 2 1/2 bags of cocoa powder.
