### Theory:

i) Proper fraction:
A proper fraction is a fraction where the value of the numerator will be lesser than the value of the denominator.
Example:
$\frac{2}{3},\phantom{\rule{0.147em}{0ex}}\frac{12}{13},\phantom{\rule{0.147em}{0ex}}\frac{50}{52}$
ii) Improper fraction:
An Improper fraction is a fraction where the value of the numerator will be greater than or equal to the value of the denominator.
Example:
$\frac{7}{6},\phantom{\rule{0.147em}{0ex}}\frac{2}{1},\phantom{\rule{0.147em}{0ex}}\frac{1}{1}$
iii) Mixed fraction:
A mixed fraction is a combination of a whole number and a proper fraction.
Example:
$2\frac{4}{5},\phantom{\rule{0.147em}{0ex}}4\frac{6}{7},\phantom{\rule{0.147em}{0ex}}6\frac{7}{8}$
iv) Unit fraction:
Fractions which has numerator as $$1$$ and denominator as any positive integer are unit fractions.
Example:
$\frac{1}{16},\phantom{\rule{0.147em}{0ex}}\frac{1}{4},\phantom{\rule{0.147em}{0ex}}\frac{1}{12}$
