Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Based on the question we can see that there is a ratio of 80 children for every 48 adults. Basically we already have the ratio, what we need to do know is simplify this ratio to make it clearer to understand.
As we can see from the calculation above there is a ratio of 5 children for every 3 adults.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

rectangle: length times width
circle: pi x r^2
trapezoid: h(base1 + base2)
and triangle: (b x h)/2
