6.1.4 Estimate Quotients

Definitions: 

• Compatible Numbers --> Numbers that are easy to divide mentally

  • • Examples:  25 and 5,   80 and 10,   35 and 7,   18 and 3   

    • You will notice on each of the examples above that the lower number goes into the higher number without a remainder

• Dividend --> The number being divided 

  • • Example:  In the problem 54 ÷ 6 <---- 54 is the dividend

    • It is also the number that goes inside of the division box when working it out by hand

• Divisor --> The number that we will divide the dividend by

  • • Example:  In the problem 54 ÷ 6 <---- 6 is the divisor

    • It is also the number that goes outside of the division box when working it out by hand

• Quotient -->  The answer to a division problem

• Dividend ÷ Divisor = Quotient
