The way to distinguish divisor and dividend is: in the division formula, the number after the division sign is called the divisor, and the number before the division sign is called the dividend.
1. The division of two numbers is also called the ratio of two numbers. If ab=c (b ≠ 0), the operation of using the product c and the factor b to find another factor a is division. Write c ÷ b, read as c divided by b (or b divided by c). Among them, c is called the dividend, b is called the divisor, and the result of the operation, a, is called the quotient.
2. The operation of finding the other factor by knowing the product of two factors and one of them is called division. Dividend ÷ divisor=quotient, dividend ÷ quotient=divisor, quotient x divisor=dividend.
