2÷4 Whether this simple formula expresses multiple meanings:1. Divide 2 into 4 parts, and take the quantity of one part.2. Find the number of 4 in 2.
1. Divide 2 into 4 points, for example, you have 2 yuan, you want to divide equally among 4 people, then how much does each share? 2÷4=0.5
2. Ask for the number of 4 in 2, for example, you have 20 yuan, and your money is 5 yuan each, then how many do you have? 20÷5=4, So you understand better. Similarly, if you have 2 yuan, and your money is 4 yuan each, then how many? 2÷4=0.5, Which means you only have half a sheet
