When x is divided by y, we write
Thus, we have
If and are two rational numbers such that , then
Dividend: The number to be divided is called the dividend.
Divisor: The number which divides the dividend is called the divisor.
Quotient: When dividend is divided by the divisor, the result of the division is called the quotient.
If is divided by , then is the dividend, is the divisor, and
is the quotient.
Example: Divide:
