Topic 3: Fractions, Percentages and Decimals – Sample Activity

A school has organised a sports tournament among the 4 teams of the school: Nile, Kafu, Kagera, and Ssezibwa. The games master has been provided with UGX 2,000,000 to be shared amongst the four houses as follows: There were four games to participate in and the houses’ performance was shown below:

Tasic Help the games master share the money amongst the participating houses. In your opinion, how do you think you can benefit from sports?

Remember

• You can get equivalent fractions by multiplying or dividing the numerator and denominator by the same number.
• A fraction is improper if the numerator is bigger than the denominator. It is proper if the numerator is smaller than the denominator.
• Some things such as human beings cannot be represented in decimal fractions but rather in whole numbers, so in case of a decimal, round off to the nearest whole number,
• You can easily add or subtract fractions if they have the same denominator.
• Terminating decimals have a finite number of digits after the decimal point while Non terminating decimals have an infinite number of digits after the decimal point. J
• A recurring fraction is usually represented by placing a dot or a bar on the repeating numbers.
• Percentage means out of every one hundred (100).
