Solutions:
we are given that Fred the clown can create 20 animal balloons every 15 minutes.
It mean that Fred the clown can create[tex]\frac{20}{15}[/tex] baloons every minutes.
In 6 hr and 45 minutes, we have a total of [tex]6\times60+45=360+45=405minutes[/tex]
So total number of balloons created can be found by multiplying the number of ballons created in one minutes by total number of available minutes.
So number of balloons created[tex]=405\times\frac{20}{15}= 540[/tex]
It mean that Fred can create 540 balloons in 6 Hrs and 45 minutes.
