i kinda did ratios
2 1/2:1 =5
2:1/2 =3 1/2
The red ball weighs about 1.4
the green ball weighs about 1.44
So i think 8r and 8g ball weighs about 22.72
This is not an exact measurement of each balls, just an estimate.
Wow... 1/2 of a ball. :-)
I see what you were trying to get across... but our teacher never showed us a problem like this... so frustrating.
I don't know if your ratio way is exactly right, but it is a good way to straighten out the info.
Wait... I got something!
g is green and r is red.
5g + 2r = 10
g + 4r = 7
Then, if we add those together and find out what one ball weighs individually, then you just multiply it by 8! I think I got it! :-)
yeah that makes sense... i'm gonna try it.
Yes, Chopsticks, after trying the way I described in my last response, I got the same answers you have.
Thank you for your help! :-)
