20 divided by 5 equals 0.25, and the difference between 20 divided by 5 and 20 divided by 5: 20 divided by 5 equals 5 divided by 20, that is, 5 ÷ 20 = 0.25; And 20 divided by 5 is 5 divided by 20, which means 20÷5=4. Only the divisor comes first and the dividend comes last; Division is the preceding dividend and the following dividend.
Division is one of the four operations. The product of two factors, one is a non-zero factor, and the operation of finding the other factor is called division. Division and division both represent division operation and two different readings of division formula.
There are two ways to read the division between two numbers, namely "division" and "division".
Divide the dividend first, then watch it, then watch it. For example, "15÷3" is pronounced as "15 divided by 3" or "3 divided by 15". 15 divided by 3 means "use" or "take", and "15 divided by 3" can be interpreted as 15 divided by 3. And "3 divided by 15" is 3 divided by 15.
Divided by divisor/dividend, divided by dividend/dividend.
The business nature of the division is as follows:
The dividend is enlarged (reduced) by n times, and the quotient is correspondingly enlarged (reduced) by n times under the condition that the divisor is unchanged.
The divisor is expanded (reduced) by n times, while the dividend is unchanged, and the quotient is correspondingly reduced (expanded) by n times.
