1. Let's assume that a bag of rice weighs x kilograms, so a bag of rice is (220-x) kilograms.
2. If a bag of rice is half eaten, there is half left, and the remaining mass is x/2. Similarly, what is the remaining rice in bag B (220-x)? 2/3
3, equation, because the ratio of the remaining mass of two bags of rice is 5:8, so the equation is: x/2 ratio (220-x)? 2/3 = 5: 8, calculate X, this is the weight of a bag of rice, and I don't need to say B bag.
