Answer:

[tex]1.\ \frac{2}{5}\ and\ \frac{1}{4}\ are\ Dissimilar\ fraction[/tex]

[tex]2.\ \frac{4}{8}\ and\ \frac{3}{4}\ are\ dissimilar fraction.[/tex]

[tex]3.\ \frac{2}{9}\ and \frac{1}{3}\ are\ dissimilar fraction.[/tex]

[tex]4.\ \frac{5}{10}\ and\ \frac{1}{2}\ are\ similar fraction.[/tex]

[tex]5.\ \frac{2}{7}\ and\ \frac{3}{5}\ are\ dissimilar fraction.[/tex]

Step-by-step explanation:

Similar fractions are fractions with different numbers representing the same part of a whole.

For example:

[tex]\frac{x}{y} =\frac{n.x}{n.y}[/tex]        

To find a similar fraction, we need to multiply by the same number in the numerator and denominator.

[tex]\frac{2}{5} \neq \frac{1}{4}[/tex]

[tex](\frac{4}{8} = \frac{1}{2})\neq \frac{3}{4}[/tex]

[tex]\frac{2}{9} \neq \frac{1}{3}[/tex]

[tex](\frac{5}{10}=\frac{1}{2})=\frac{1}{2}[/tex]

[tex]\frac{2}{7}\neq \frac{3}{5}[/tex]
