ASSIGNMENT 4:

Question 1
1.1. a) Ordinal numbers represent the position or order of something in a sequence. They do not
represent the quantity, but rather the position of the object. For example, 1st, 2nd, 3rd, 4th, etc.
Example: A race with 4 runners, where they finished in order: 1st, 2nd, 3rd, 4th.
b) Cardinal numbers represent the quantity of something, or how many there are. For example, 1,
2, 3, 4, etc. Example: A basket containing 4 apples.
c) Nominal numbers are used to label or identify something. They do not represent quantity or
order. For example, the names of people, places, or things. Example: A group of 4 people with
their names written down.
1.2. Fractions, decimals, and percentages are all different ways of representing the same value. A
fraction is a part of a whole, where the top number (numerator) represents how many parts are
taken and the bottom number (denominator) represents the total number of parts in the whole.
Decimals and percentages are just different ways of expressing fractions.
For example, if we take the fraction “two thirds”, we can convert it into a decimal by dividing the
numerator (2) by the denominator (3), which gives us 0.66666667 (rounded to 2 decimal places).
We can convert it to a percentage by multiplying the decimal by 100, which gives us 66.67%.
