In the given figure, four parts are not equal.
∴ Fraction is not equal to 1/4.

Total number of equal parts = 2; Shaded parts = 1
 ∴ Fraction representing the shaded portion = \(\frac { 1 }{ 2 } \)

Total number of equal parts = 10; Shaded parts = 10
 ∴ Fraction representing the shaded portion = \(\frac { 10 }{ 10 } \)

Total number of equal parts = 4; Shaded parts = 1
 ∴ Fraction representing the shaded portion = \(\frac { 1 }{ 4 } \)

\(\frac { 2 }{ 9 }\)and \( \frac { 6 }{ 27 } \) Here 2\(\times\)27 =54 and 9\(\times\)6 = 54
∵ 54 = 54, so \(\frac { 2 }{ 9 } \)and \(\frac { 6 }{ 27 } \) are not equivalent fractions

\(\frac { 2 }{ 5 } \)and \(\frac { 2 }{ 7 } \) Here 2\(\times\)7 =14 and 5\(\times\)2 = 10
∵ 14 ≠ 10, so \(\frac { 2 }{ 5 }\)and ​​​​​​​\(\frac { 2 }{ 7 } \) are not equivalent fractions.

\(\frac { 1 }{ 3 } \)and \(\frac { 2 }{ 7 } \) Here,1\(\times\)7 = 7 and 3\(\times\)2 =6
∵ 7 ≠ 6, so \(\frac { 1 }{ 3 } \)and \(\frac { 2 }{ 7 } \) are not equivalent fractions.

Here, fractions are\(\frac { 1 }{ 2 } ,\frac { 1 }{ 4 } ,\frac { 3 }{ 4 } ,\frac { 4 }{ 4 } \)  Also  \(\frac { 1 }{ 2 } =\frac { 1\times 2 }{ 2\times 2 } =\frac { 2 }{ 4 } \)
Now, draw a number line, mark two points 0 and 1on it. Divide the gap between 0 and 1 into four equal parts because denominator is 4, then each part will show\(\frac { 1 }{ 4 } \) Also, 2 parts show\(\frac { 2 }{ 4 } \), 3 parts show \(\frac { 3 }{ 4 } \) and 4 parts show \(\frac { 4 }{ 4 } \)

Here A, B, C and D represent \(\frac { 1 }{ 2 } ,\frac { 1 }{ 4 } ,\frac { 3 }{ 4 } ,\frac { 4 }{ 4 } \) respectively.

(i) Total number of equal parts = 2;
Number of shaded parts = 1
∴ Fraction of shaded portion = \(\frac { Number\ of\ shaded\ parts\ }{ Total\ number\ of\ equal\ parts } =\frac { 1 }{ 2 } \)
(ii) Total number of equal parts = 4;
Number of shaded parts = 2
∴ Fraction of shaded portion = 2/4
(iii) Total number of equal parts = 6;
Number of shaded parts = 3
∴ Fraction of shaded portion = 3/6
(iv) Total number of equal parts = 8;
Number of shaded parts = 4
∴ Fraction of shaded portion = 4/8
Now, \(\frac { 2 }{ 4 } =\frac { 2\div 2 }{ 4\div 2 } =\frac { 1 }{ 2 } \)  [∵ HCF of 2 and 4 is 2]
\(\frac { 3 }{ 6 } =\frac { 3\div 3 }{ 6\div 3 } =\frac { 1 }{ 2 } \)  [∵ HCF of 3 and 6 is 3]
\(\frac { 4 }{ 8 } =\frac { 4\div 4 }{ 8\div 4 } =\frac { 1 }{ 2 } \) [∵ HCF of 4 and 8 is 4]
Since all fraction in simple form are same.
∴ \(\frac { 1 }{ 2 } =\frac { 2 }{ 4 } =\frac { 3 }{ 6 } =\frac { 4 }{ 8 } \) i.e the fractions are equivalent.
