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.
