Solve without algebraic equation:
After 1/6 of a barrel of rice was eaten, 10 kg of the rice was left over. How many kg of rice would be left over if 1/4 of the rice had been eaten instead?
Answer provided by our tutors
The least common measure for 6 and 4 is 12.
1/6 = (2*1)/(2*6) = 2/12
2/12 of the rice was eaten and 10/12 or 10 kg was left over.
This means that 1/12 equals 1 kg.
1/4 = (3*1)/(3*4) = 3/12
If 3/12 of rice is eaten this means 9/12 is left over or 9 kg is left over.
