# Mixing pait with ratios

I was wondering if any of you could solve the following equation,

Green paint and yellow paint can be mixed in the ratio 4:7 to make a certain lime colored shade. If a painter has 500 ml of green and 650 ml of yellow, what volume of lime colored paint can be made?

I have tried to solve this by using up all the green paint, and then using what is left of the yellow paint, however, I get confused when I do this. I also tried to add 500 and 650 to make it easier, but this does not work either.

Thank a lot!

• For the purpose of making lime green paint, it is the yellow paint that is in short supply. Use it all. Dec 30, 2015 at 23:41
• Hi, thanks for your reply, I have done that, but what would I do next? Dec 30, 2015 at 23:56
• Either then calculate the amount of green paint used, and add, or more simply multiply $650$ by $\frac{11}{7}$. Dec 31, 2015 at 0:04
• Where did you get the number 11/7 from? Dec 31, 2015 at 0:23
• If there are $7$ yellow to every $4$ green, for every $7$ yellow we get $11$ of mixture. Dec 31, 2015 at 0:24
