What's the answer please answer

I think it’s 4 9/10 ounces of green paint.
okay so first change the whole numbers into fractions so 3 1/2 would become 7/2, and 1 2/5 would be 7/5. Then you need to find the common denominator which would be 10. so 7/2 would become 35/10, and 7/5 would be 14/10. add 35/10 and 14/10 to get 49/10. 49/10 is 4 9/10! tell me if you need a better explanation,, or if i confused you :]
