Question

A pizza shop uses $\frac{31}{2}$ packets of bacon, $\frac{47}{2}$ packets of sausages, and $\frac{180}{4}$ packets of cheddar cheese in a day. What is the total number of these packets used in a day?

• A. $\frac{163}{2}$ packets
• B. $\frac{168}{2}$ packets
• C. $\frac{168}{4}$ packets
• D. $\frac{173}{2}$ packets

Answer 1

The correct option is B $\frac{168}{2}$ packets

Total packets used = Packets of bacon + Packets of sausages + Packets of cheddar cheese

$=\frac{31}{2}+\frac{47}{2}+\frac{180}{4}$

$=(\frac{31}{2}+\frac{47}{2})+\frac{180}{4}\text{[Associative property]}$

$=\frac{78}{2}+\frac{90}{2}$

$=\frac{168}{2}$ packets or $84$ packets in total.
