Jamal and his mother traveled for 2 and 5/8 hours. he spent 2/3 of the time in the car sleeping and the rest of the time playing video games. how many hours did jamal spend playing video games?

So what you do is subtract 2 and 5/8 from 2/3. 

1. make the denominators the same by using GCD
8                       | 3
8*1=8               | 3*1=3 
8*2=16             |3*2=6
8*3=24             |3*3=9    
8*4=32             |3*4=12
8*5=40             |3*5=15
8*6=48             |3*6=18
8*7=56             |3*7=21
8*8=64             |3*8=24
8*9=72             |3*9=27
8*10=80           |3*10=30

2. find which ones they have in common, and use GCD to solve for the denominator
8 and 3 both have 24
so the GCD is 24

3. put your new problem in there
2 and 5/24 - 2/24= x

4.solve your problem for x
2 and 5/24 - 2/24= 2 and 3/24

5. now simplify 2 and 3/24
2 and 3/24 divided by 3= 2 and 1/8

6. so you can say
x = 2 and 1/8

 

Sorry to break it to you but this is mathmatics NOT english lol!!
