i kinda did ratios

5:2 =10

4:1 =7

8:8 =?

so then

2 1/2:1 =5

2:1/2 =3 1/2

4:4 =?

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!

Maybe it's...

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! :-)

just reposting :):):)
