1. Write the fraction representing the shaded portion.
Solutions:
(i) Number of parts = 4
Shaded portion = 2
∴ Fraction = 2 / 4
(ii) Number of parts = 9
Shaded portion = 8
∴ Fraction = 8 / 9
(iii) Number of parts = 8
Shaded portion = 4
∴ Fraction = 4 / 8
(iv) Number of parts = 4
Shaded portion = 1
∴ Fraction = 1 / 4
(v) Number of parts = 7
Shaded portion = 3
∴ Fraction = 3 / 7
(vi) Number of parts = 12
Shaded portion = 3
∴ Fraction = 3 / 12
(vii) Number of parts = 10
Shaded portion = 10
∴ Fraction = 10 / 10
(viii) Number of parts = 9
Shaded portion = 4
∴ Fraction = 4 / 9
(ix) Number of parts = 8
Shaded portion = 4
∴ Fraction = 4 / 8
(x) Number of parts = 2
Shaded portion = 1
∴ Fraction = 1 / 2
2. Colour the part according to the given fraction.
Solutions:
3. Identify the error, if any.
Solutions:
(i) The shaded portion is not half
Hence, this is not 1 / 2
(ii) Since, the parts are not equal
∴ Shaded portion is not 1 / 4
(iii) Since, the parts are not equal
∴ Shaded portion is not 3 / 4
