Mariana mixes yellow and blue paint in a ratio of 2 : 5 to make green paint. She pours the yellow and blue paint into a large can to mix it. When the can is full, she realizes she wants to create a darker green and fills the rest of 7/8 the can with blue paint. What ratio of yellow to blue paint should Mariana use if she wants to create this same green color in the future?

you still haven't said
(a) how more paint can be added when the can is full
(b) just what "the rest of 7/8 the can" means
No matter how many times you post this garbled question, no one will be able to help.
