Answer:
19:10- 1.9:1
Explanation:
Remember that to calculate ratio you can do it just by putting together both values and see if the can be smaller, since this cannot be reduced any further, that would be your ratio 19:10 meaning that for every 19 games there are 10 rides, if you´d need a unit rate, then that would be 1.9:1 because remember that unit rates always use 1 as numerator.
