We have already seen that fractions can be equal to whole numbers. In the case of the chocolate cake we saw that \(\frac{3}{3}=1\)
Similarly,
\[\frac{4}{4}=1\]
\[\frac{16}{16}=1\]
\[\frac{1017}{1017}=1\]
Any whole number (integer) can also be written as a fraction. The simplest way to write a whole number as a fraction is by having the whole number as the numerator, and 1 as the denominator.
\[2=\frac{2}{1}\]
\[3=\frac{3}{1}\]
\[4=\frac{4}{1}\]
and
\[1=\frac{1}{1}\]
\(2=\frac{2}{1}\) can be expressed in words as
two equals two over one
or
two equals two on one
or
two equals two divided by one.
(The line between the numerator and denominator is a way of representing the mathematical operation of division.)
