12. 36 ÷ 5 = 7.2 Division Vocabulary
The dividend is the number that is being divided.
The divisor is the number that the dividend will be divided by.
The quotient is the number of times the divisor will go into the dividend. (The answer to the division problem.)
dividend ÷ divisor = quotient or quotient
divisor )dividend
In this example 5 is the divisor, 36 is the dividend, 7.2 is the quotient.
7.2
36 ÷ 5 = 7.2 5 )
