tom had 45 marbles. he gave some to dan. he had 19 marbles left. how may marbles did he give to dan?
make it out of 100, so 40 times 2.5 equals 100 and 18 times 2.5 equals... 45 so its 45 percent
18 / 45 = 0.4 (so there are 40% girls) 1 - 0.4 = 0.6 (so there are 60% boys)
%*amount=answer .45*45=answer answer=20.25 boys. so i would round it to 20 boys..

The poorly worded question leaves doubt as to what the answer is. If Ken gave Andrew 10 more marbles, and Andrew ends up with a hundred, Andrew started with 90. If Ken gave him the same number Andrew already had plus ten to equal 100 marbles, Andrew started with 45 and Ken gave him 55.
