Division of Whole Numbers I. Definition of Division Example: Suppose that we have twelve students in the class and we want to divide the class into three equal groups. How many should be in each group? Solution: We can ask the alternative question, "Three times what number equals twelve?" The answer to this question is four. Division is defined as this reverse of multiplication. We write 4 3 | 12 or 12 ÷ 3 = 4 We call the number 12 her the dividend , the number 3 the divisor , and the number 4 the quotient . quotient divisor | dividend or dividend ÷ divisor = quotient II. Properties of Division A. Division by Oneself Example Suppose that you had $100 and had to distribute all the money to 100 people so that each person received the same amount of money. How much would each person get? Solution If you gave each person $1 you would achieve your goal. This comes directly from the identity property of one. Since the the questions asks what number times 100 equals 100. In general we conclude, Any number divided by itself equals 1 Examples

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
