The mass of a container is 5.81 kilograms when completely filled with sugar. The mass of the container is 3.8 kilograms when 3/8 of sugar is removed. What is the mass of the empty container?
If 3/8 of sugar removed then
5.81-3.8=2.01 kilograms is the mass of 5/8 of sugar.
So mass of the whole sugar is 3.216 kilograms (divide 2.01 by 5 and multiply with 8)
5.81-3.216=2.594 kilograms is the mass of container
