Introduction
What is a percentage ?
A percentage shows the size of a value in relation to a whole, where the whole is defined as being 100 and not forgetting that percentages are always expressed as a fraction out of 100.
Calculating percentages
- To calculate a percentage (%) we always determine the fraction of 100, e.g. take the fraction and multiply it by 100.
an example write 6/7 as a percentage.
6/7x100=85,71.
Task
1.1 Calculate 15% of R180
1.2 Calculate 18% of R200
1.3 Calculate 85% of R890
1.4 Calculate 60% of R2000
1.5 Calculate the increase and add it to the original amount
20% of 300.
Process
These are the formulas to calculate the percentage:-
given percentage/100 x given amount =
Percentage increase= Given percentage/100 x given amount = Answer
Answer + Given amount =
Evaluation
Memorandum
1.1 15/100 x R180= R27
1.2 18/100 x R200= R36
1.3 85/100 x R890= R756.5
1.4 60/100 x R2000= R1200
1.5 20/100 x 300= R60
R60 + R300 = R360
Conclusion
-asks the learner where they are lacking with the activity we just did.
- Will try to explain what learners dont understand so that we can all be in asame page
- will give learners a home to complte when they get home.
