Question

A food court uses \(\dfrac{31}{2}\) packets of bacon, \(\dfrac{47}{2}\) packets of sausages, and \(\dfrac{180}{4}\) packets of cheddar cheese in a day. What is the total number of these packets used in a day?

Answer 1

Total packets used \(=\) Packets of bacon \(+\) Packets of sausages \(+\) Packets of cheddar cheese
\(=\dfrac{31}{2}+\dfrac{47}{2}+\dfrac{180}{4}\)
\(=\left ( \dfrac{32}{2}+\dfrac{47}{2} \right )+\dfrac{180}{4}\) [Associative property]
\(=\dfrac{78}{2}+\dfrac{90}{2}\)
\(=\dfrac{168}{2}\) packets or \(84\) packets in total
