(1/21) × 987 = □ Answer: 47
(1/21) × 1008 = □ Answer: 48

How it works

Choose a title and 1–12 sheets. Each sheet uses the next edition number. Print the puzzle first, then reveal the answers for a separate teaching copy.

Print the question sheet before revealing answers. A new edition changes the exercise selection and order, while keeping the same learning goal.
