Elementary school mathematics problem fifth grade multiple
The second bag is 40 kilograms heavier than the first one. If you take 5 kg from the second bag and pour it into the first bag, the weight of the second bag of rice is exactly three times that of the first bag. How much does the first bag of rice weigh in the second bag? How many times the weight of the second bag is that of the first bag? The second bag is 40 kilograms heavier than the first one. If you take out 5 kilograms from the second bag and pour it into the first bag, the second bag is 5 kilograms less and the first bag is 5 kilograms more. In fact, the second bag is 65,438+00 kilograms lighter than the first bag. At this time, the weight of the second bag is only 40-65, 438+00 = 30 kg, and the weight of the second bag is just three times that of the first bag. 30÷2= 15 kg, the first bag is 5 kg,15 =10 kg, and the second bag is 10+40=50 kg. It turns out that the first bag of rice is 1 of the second bag, and the second bag weighs 1.
