Number theory Difficulty 1.4 Junior Find the answer Canada

At a factory, 1141011\,410 kg of rice is distributed equally into 32603260 bags. A family uses 0.25 kg of rice each day. How many days would it take this family to use up one bag of rice?

Pick one

Solution

Since 11 410 kg of rice is distributed into 3260 bags, then each bag contains 11410÷3260=3.511\,410\div3260=3.5 kg of rice.

Since a family uses 0.25 kg of rice each day, then it would take this family 3.5÷0.25=143.5\div0.25=14 days to use up one bag of rice.
