Great job!
Just one small correction. The correct amount is 680, not 640.
Your method is correct. Just redo it with the correct number.

oh lol! thank you very very much <3, how did you know it was a proportion problem?

mathstudent55 · Answer

The info the problem gives you is a ratio.
17 g of sugar to 240 ml of drink is a ratio.
Then you have another ratio containing an unknown.
That is: x g of sugar to 680 ml of drink.
A proportion is defined as setting two ratios equal to each other.
