Lets us assume the total # of player to be 90. 45 Right handed and 45 Left Handed
# players present for practice is 30
# of Left hand players present for practice is 10
# of Left hand players not present for practice is 30
# of Right hand players present for practice is 20
# of Right hand players not present for practice is 25
Required Ratio is 25/35 = 5/7

Best strategy, pick a number, which can be divided by 9. Choose Total no of Players such as 90, 180....
