this is a grade 9 lesson on fractions, its also a revision

1. FRACTIONS
GRADE 9
PRESENTED BY
ZAMOKWAKHE XIMBA

2. LESSON OUTCOME
 At the end of the lesson the learner should
be able to:
 Identify and explain fractions
 Solve problems of fractions
 Be able to apply fractions in real world

3. What are fractions?
A fraction is the ratio of two whole
numbers, or to put it simply, one whole
number divided by another whole
number. We write a fraction like this ¾

4. Fractions cont….
 The top part of the fraction is called the
numerator and is also referred to as the dividend
of the fraction. The bottom part is called the
denominator and is also referred to as the divisor
of the fraction.
 Normally the numerator (top of fraction) is smaller
than the denominator (bottom of fraction) in
which case the fraction is called a 'Proper
Fraction'. If the numerator (top) is equal to or
larger than the denominator (bottom) then the
fraction is called an 'Improper Fraction'.

5. SOLVING PROBLEMS

8. FRACTIONS AS PERCENTS

9. EXAMPLE
 Ifa learner gets a ten out of 100 in a test it
can be written as 10/100
 That is the same as 1/10
 50% = 50/100 =1/2

10. Write as a fraction or mixed
number in Simplest Form
 10%
 49%
 58%
 150%
 1st:
Write as the % over 100 #/100
 2nd: Simplify.

11. APPLICATION OF FRACTIONS
IN THE REAL WORLD
 Five out of sixteen families in the Argentina
own Penguins. What percent of families
own Penguins?
 1st: Write as a fraction.
 2nd: Divide the numerator by the
denominator.
 3rd: Write as a percent.

12. INVESTIGATION
 Investigate the percentage how many
people die compared to those who are
born?
 What is the ratio between the people in
Africa and those in Asia?
 Investigate the relationship between
