Write the fractions representing the shaded regions and pair up the equivalent fractions from each row:

The fractions representing the shaded regions are:

(i) Total parts = 2

Shaded parts = 1

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{1}{2}$.

Hence, fraction = $\dfrac{1}{2}$

(ii) Total parts = 6

Shaded parts = 4

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{4}{6}$.

Hence, fraction = $\dfrac{4}{6}$

(iii) Total parts = 9

Shaded parts = 3

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{3}{9}$.

Hence, fraction = $\dfrac{3}{9}$

(iv) Total parts = 8

Shaded parts = 2

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{2}{8}$.

Hence, fraction = $\dfrac{2}{8}$

(v) Total parts = 4

Shaded parts = 3

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{3}{4}$.

Hence, fraction = $\dfrac{3}{4}$

(a) Total parts = 8

Shaded parts = 2

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{2}{8}$.

Hence, fraction = $\dfrac{2}{8}$

(b) Total parts = 12

Shaded parts = 8

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{8}{12}$.

Hence, fraction = $\dfrac{8}{12}$

(c) Total parts = 16

Shaded parts = 12

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{12}{16} = \dfrac{3}{4}$.

Hence, fraction = $\dfrac{3}{4}$

(d) Total parts = 8

Shaded parts = 4

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{4}{8}$.

Hence, fraction = $\dfrac{4}{8}$

(e) Total parts = 9

Shaded parts = 3

Fraction = $\dfrac{\text{Shaded parts}}{\text{Total parts}} = \dfrac{3}{9}$.

Hence, fraction = $\dfrac{3}{9}$

Hence, the equivalent pairs are:

(i) ↔ (d), (ii) ↔ (b), (iii) ↔ (e), (iv) ↔ (a), (v) ↔ (c).
