(applications skills and critical
thinking skills)
4. FRACTIONS, DECIMALS AND PERCENTAGE
These topics are related with one another.
Concept is less than one
⅜ of the questions asked are related to the topics
above.
Fractions - on denominators
Decimals - decimal points
Percentage - X 100 %
Usually asked on problem solving questions
fractions multiply a whole number
Look for key words in the questions and understand
what is asked for.
Practice on completing fractions and understand
vocabulary related to the topics.
5. MIXED OPERATIONS AND AVERAGE
Has its own principles and formulas.
Mixed Operation - BO DM AS
For MT 015/2, you must show your workings clearly and make
sure you are confident with your workings. Do not
show 2 methods and expect the teacher to choose for
you. Jumlah Jumlah
Purata = Bilangan =
Average -
Bilangan Purata
Jumlah = Purata × Bilangan
Questions on Average for MT 015/1 are usually on how to
find the total when the average is given.
For finding the total :
a. Multiply average with number of quantities.
b. add all the number of quantities given.
c. product (a.) take away with the total (b.)
d. if asked for 2 equal amount- divide by 2
6. MONEY
Value for RM and sen.
write sen in RM vice - versa.
Operation involving conversion of value.
Problem solving involving:
1. Tables
2. Incomplete bills
3. Income and Spending
4. Percentage, fractions
5. Average
6. Mixed Operations
7. Cost Price and Selling Price – Profit and Loss
Bare in mind that questions on problem solving on
Money also involves combination of other topics and
skills.
7. SHAPE AND SPACE
Must have sides or boundaries
Shapes like rectangles, squares, triangles, circles and
others.
Combination of shapes and solids
Know the characteristics of shapes and solids
Recognize the sides of the shape or solids
Use the formulas for finding:
1. perimeter - adding all outer sides
2. Area of - length x width/breadth
Area of - base x height ÷ 2
3. Volume - length x width x height
Questions on Problem Solving on this topic will also
include fraction, percentage and money.
Important: you must also know how to find the sides.

18. Technique Of Answering Mathematics Paper 2 Questions (015/2)
1. Technique of constructing and copying tables
If you are not able to remember your tables/how to
convert units, write down the tables/units first before
you start answering the questions.
2. Technique of answering diagrams/tables
For questions on diagrams/tables (esp. questions on
perimeter, measurements tools etc.) it is best for you
to write down the appropriate units or hidden
information before you continue to solve the problem.
19. Technique of Answering Mathematics Paper 2 (015/2)
3. Technique of drawing diagrams or tables
For questions on problem solving which do not show any
diagrams or tables, it is better for you to understand the
question by drawing diagrams or tables or jotting down the
important notes.
4. Important:
Questions on problem solving must be solved systematically
or follow the correct steps.
20. Notes:
a. All workings must be shown clearly.
You may lose marks if you do not
show the correct steps.
Please do your work
systematically.
21. Note:
b. Do not send booklet that is not
answered.
It is better for you to answer part
of the question than leaving it blank.
You may get some marks for the part
that you have answered.
22. Note:
c. Use 2B pencil when answering all
questions.
Answers must be neat, clear and
systematic.
Your booklet must be clean.
Do not draw or scribble anything that is
not asked for.
23. Remember!
Do not forget to check your workings
