Owen received $100 for his birthday. he wants to spend 2/10 of his money on a video game. he wants to spend 55/100 of his money on a skateboard. he wants to spend 3/10 of his money on comic books. what fraction of his birthday money does owen want to spend? does he have enough money ?

An easy way to solve fraction problems like this is to make each fraction have the same denominator.  Since he has $100, the denominator will be 100.
2/10=?/100    10*10=100  1*10=20   20/100 of his money he wants to spend on video games
55/100 already has 100 as its denominator, so he wants to spend 55/100 on a skateboard.
3/10=?/100   10*10=100   3*10=100  30/100 is how much he wants to spend on comic books.
Add all of the fractions together to see how much he wants to spend and if he has enough.
20/100+55/100+30/100=105/100
He wants to spend $105, which is $5 more than he has.
