To make this problem easier you could make the denominators equal to combine the 2 bills to see how of his paycheck is being used already. to 2/7 = 6/21 and 1/3=7/21 so with 6/21 and 7/21 you can combine them and you have 13/21 is used on bills so 21/21(which represents the whole paycheck) - 13/21 =8/21 so 8/21 is what is left his paycheck to spend write this as a decimal by dividing and you will have the percentage that he has left  so 8/21 = .38 so he can spend approximately 38% of his check on games and 63dollars * .38 is about 24dollars 63*.38 =24(approximately) you divide 8/21 and get an exact answer.
