1.1. Explanation of Improper, Mixed, and Proper Fractions (6
Marks)
Proper Fraction: A fraction where the numerator (top number) is smaller than
the denominator (bottom number). For example, }. This shows that we have
less than a whole.

Improper Fraction: A fraction where the numerator is larger than or equal to
the denominator. For example, • This means we have more than one whole.

Mixed Fraction: A fraction that includes a whole number and a proper
fraction. For example, 24, which means 2 whole parts and 4 of another part.

1.3. Fractions, Decimals, and Percentages Relationship (6
Marks)


Fractions to Decimals: To convert a fraction to a decimal, divide the
numerator by the denominator. For example, 5 is:
V
2:30.666... (repeating)




Fractions, decimals, and percentages are all ways to represent parts of a whole.

• Fractions to Decimals: To convert a fraction to a decimal, divide the
numerator by the denominator. For example, f is:
2 + 3 - 0.666.. (repeating)
ractions to Percentages: To convert a fraction to a percentage, multiply the
fraction by 100. For #:
2
x100 -- 66.66%

Two examples:

=0.5(decimal) = 50% (percentage)

}=025(decimal) = 25% (percentage)
