, Question 1 (25 marks)
1.1. Write down the following number in words: 7 245 103 (3)
Seven Million Two Hundred and Forty-Five Thousand One Hundred and Three
1.2. Match the nation to its numeration system.
Column A (nation) Column B (numeration system)
Egyptians Hieroglyphics
Roman Roman Numerals
Greek Attic Systems
Indian Hindu Numerals
1.3. Distinguish in detail among cardinal, ordinal and nominal numbers. Give
examples by referring to the picture below. (6)
Cardinal numbers are the numbers that are used for counting something. These
are also said to be cardinals. The cardinal numbers are the counting numbers that
start from 1 and goes on sequentially and are not fractions. The examples of
cardinal numbers are: 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
Ordinal numbers are the numbers which indicate the exact position of something or
someone at a place. All the ordinal numbers in Maths are natural numbers or
counting numbers.
A Nominal Number is a number used only as a name, or to identify something (not
as an actual value or position) Other examples the number on the back of a player:
"8",A zip code: "91210",A model number: "380"
1.4. The price of a Grade 4 mathematics textbook is discounted by 15%. The old
price was R350,00. Calculate the discount price. (3)
0.15 x R350.00 = R52.50
R350.00 – R52.50 = R297.50
1.5. The sale price of a laptop is R3 700,00, which is only 65% of the original
price. Calculate the original price. (3)
65% of X = 3700
= 65/100 x X = 3700
X = 3700/1 x 100/65
x = 370 000/65
x = R5692.30 (Original Price)
1.6. Mr Dhlamini is a Grade 4 teacher. There are 15 boys and 10 girls in his
mathematics class.
