ALGEBRA: Mathematical Operations with Algebraic Terms- Division

LESSON 6

ALGEBRA: Use of Letters in Mathematics

MATHEMATICAL OPERATIONS WITH ALGEBRAIC TERMS

Mathematical operations are the basic operations carried out in mathematics. Examples are multiplication (x), division (÷), addition (+), subtraction (-) e.t.c.

We are going to discuss the division of algebraic terms in this lesson. Let’s go! 

DIVISION OF ALGEBRAIC TERMS

Division of algebraic terms is done by dividing the numbers in the numerator by numbers in the denominators and then doing the same to the letters. Let’s look at some examples.

EXAMPLE 1

Simplify 16h ÷ 4

SOLUTION

16h ÷ 4 = 16 X h

                    4

             = 4 X h

                   1

            = 4h

EXAMPLE 2

Simplify 3cd ÷ d

SOLUTION

3cd ÷ d = 3 X c X d

                      d

              = 3 X c X 1

                       1

                  

              = 3c

EXAMPLE 3

Simplify

8ab

2a

SOLUTION

8ab  =  8 X a X b

2a           2 X a

       =  4 X 1 X b

               1 X 1

                     

       = 4b

EXAMPLE 4

Simplify 36e²f ÷ 9ef

SOLUTION

36e²f ÷ 9ef = 36 X e X e X f

                        9 X e X f

                  = 4 X e X 1

                     1 X 1 X 1

                  = 4e

PUSH IT IN!

Simplify the divisions in the examples in your pad without looking at the solutions.

Did you get them correctly? Good, now go to the activities.

If you cannot simplify any of the examples without looking at the solution, tell me about the problem in a COMMENT and let’s solve it together.

ACTIVITY

Simplify the following

1.  28ab ÷ 4

2.  6mn ÷ 3m

3.  15c²

      5c

4.  81qp²

      3p
