Uncle Raj packs 8.4 kg of flour equally into 70 containers. What is the mass of flour in each container, in kilograms?
Need a hint?
Find one equal part by sharing the total mass among all 70 containers.
Worked answer
- Divide the total mass by the number of containers.
- 8.4 ÷ 70 = 0.12.
- Each container has 0.12 kg of flour.
Answer: 0.12 kg
