Introduction to Fractions.
Fractions express a part of a whole.
Fractions can be written using two whole numbers and a line.
Number above the line is called numerator. Number below the line is called denominator.
Denominator tells us total number of parts in a whole. Numerator tells us how many parts are taken from the whole.
Note that, denominator cannot be zero because we cannot make zero parts of a whole.
