Answer: The required simplest mixed number is \(2\dfrac{1}{2}.\)
Step-by-step explanation: We are given to write the following fraction as a mixed number in the simplest form :
\(f=\dfrac{20}{8}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\)
To convert the given number into simplest mixed fraction, first we need to cancel the common factors of both of them.
We have from expression (i) that
\(f\\\\\\=\dfrac{20}{8}\\\\\\=\dfrac{4\times5}{4\times2}\\\\\\=\dfrac{5}{2}\\\\\\=2\dfrac{1}{2}.\)
Thus, the required simplest mixed number is \(2\dfrac{1}{2}.\)
