How to solve this kind of problem in first grade mathematics?
Observing the picture, I found that the left cat's fish basket is 8, and the right cat's fish basket is 9. Each fish has a recipe. The question is who catches more fish. Two cats caught some fish. Now calculate the formula on the fish and put the fish in the corresponding fish basket to see who has more fish. After calculation, it was found that four fish got 8 and five fish got 9, so the cat on the right caught more fish.
