Equivalent
• Numerator - Number above the line in
a fraction.
• Denominator - The number below the
line in a fraction showing how many
parts the whole is divided.
• Horizontal bar - Between the
numerator and denominator.
e.g. :
4 Numerator
5 Horizontal Bar
Denominator
Unlike fractions
Fractions which do not
have same denominators.
Denominator
On the basis of
When numerator and denominator are
divided by a prime factor and after
division they both have no common factor
except 1, then it is known as the simplest
form of fraction.
Fractions which have
same denominators.

like fractions
Fractions which have fractions
numerator more
than denominator.
Fractions which have
1 as numerator.
Mixed fractions
expressed as
combination of a
whole number and a
fraction.
In case of like
fractions, fraction with
smaller numerator is
smaller and vice-versa.
Add the numerators of the
like fractions keeping the
denominator same.
