Step 1
We will discus two methods namely "Same Denominaor Method" and "Same Numerator Method".
In same "Same Denominator Method", the fraction having larget numerator is greater.
While is "Same Numerator Method", the fraction having smaller deniminator is larger.
Step 2
Using Same Denominator Method
$$\displaystyle{\frac{{{2}}}{{{3}}}}$$
$$\displaystyle{\frac{{{2}\times{5}}}{{{3}\times{5}}}}$$
$$\displaystyle{\frac{{{10}}}{{{15}}}}$$
$$\displaystyle{\frac{{{4}}}{{{5}}}}$$
$$\displaystyle{\frac{{{4}\times{3}}}{{{5}\times{3}}}}$$
$$\displaystyle{\frac{{{12}}}{{{15}}}}$$
$$\displaystyle\Rightarrow{\frac{{{10}}}{{{15}}}}{<}{\frac{{{12}}}{{{15}}}}$$
Hence, $$\displaystyle{\frac{{{4}}}{{{5}}}}$$ is greater than $$\displaystyle{\frac{{{2}}}{{{3}}}}$$.
Using Same Numerator Method.
$$\displaystyle{\frac{{{2}}}{{{3}}}}$$
$$\displaystyle{\frac{{{2}\times{2}}}{{{3}\times{2}}}}$$
$$\displaystyle{\frac{{{4}}}{{{6}}}}$$
$$\displaystyle{\frac{{{4}}}{{{5}}}}$$
$$\displaystyle{\frac{{{4}}}{{{5}}}}$$
$$\displaystyle{\frac{{{4}}}{{{5}}}}$$
$$\displaystyle\Rightarrow{\frac{{{4}}}{{{6}}}}{<}{\frac{{{4}}}{{{5}}}}$$
Hence, $$\frac{4}{5}$$ is greater than $$\displaystyle{\frac{{{2}}}{{{3}}}}$$.
