Try a sample Prime, composite, square numbers question
Question 1 — Easy
A sustainability project uses 2.5 kg of recycled material for each panel. How many kg of material are needed to make 12 panels?
Answer: 2.5 × 12 = 30 kg. Split: 2.5 × 10 = 25, plus 2.5 × 2 = 5. Total: 25 + 5 = 30 kg. Option A (14.5) adds 2.5 + 12 instead of multiplying. Option C (24) uses 2 × 12, dropping the decimal. Option D (25) only multiplies 2.5 × 10, stopping short of ×12.
Question 2 — Medium
A student buys a book for $12.50 and a pen for $3.75. She pays with a $20 note. How much change does she receive?
Answer: Total spent = $12.50 + $3.75 = $16.25. Change = $20.00 − $16.25 = $3.75.
Question 3 — Hard
Calculate: 3 ÷ ¾
Answer: Dividing by a fraction: multiply by its reciprocal. 3 ÷ ¾ = 3 × 4/3 = 12/3 = 4.
