If Maria spent 40 minutes chatting and that was 20% of her time, we can use proportions to find out long she was on the Internet:

40/x=20%/100%
Cross multiply
20x=4000
x=200 minutes spent online
Now 25% of that was spent playing games so set up another proportion 
x/200=25%/100%
Cross multiply 
5000=100x
50 minutes spent playing games

Thanks Jaminique for your help

No problem. Are you ok with the other problems? Use proportions for them all.

anonymous · Answer

So I needed is multiply the others % by the 200 hrs Maria spent online?

anonymous · Answer

Yes. For #6, multiply 200*.30 and 200*.15 
Then subtract the minutes

anonymous · Answer

#7 we already know is 200

anonymous · Answer

so for #6 Maria spend 60 minutes for research and 30 minutes for email
