Question

At a local Walmart store, a Coke dispenser held191 gallons of soda. During working hours,12gallons were dispensed. How many gallons of Coke remain?Coke remaining

Answer 1

initially, the dispenser held

`19(1)/(4)`

and it dispensed

`12(3)/(4)`

the remaining gallons are:

`R=19(1)/(4)-12(3)/(4)`

Now, let's solve this

`\begin{gathered} R=18(5)/(4)-12(3)/(4)=(18-12)+((5)/(4)-(3)/(4))=6+(2)/(4) \\ R=6(1)/(2) \end{gathered}`

so the remaining soda is 6+1/2

`6(1)/(2)`
