Accepted Solution
A:
Answer:The amount of ounce used for paint is [tex]\frac{9}{15} ounce[/tex] Step-by-step explanation:used amount for water is [tex]\frac{2}{3}[/tex] ounce.used amount for sky is [tex]\frac{3}{5}[/tex] ounce.thus, the total amount used is [tex]\frac{2}{3}[/tex] + [tex]\frac{3}{5}[/tex]= [tex]\frac{19}{15}[/tex]Thus the total unused amount is 2 - [tex]\frac{19}{15}[/tex] = [tex]\frac{11}{15}[/tex] .But the remaining amount is [tex]\frac{2}{15}[/tex].Thus used amount for flag is [tex]\frac{11}{15}[/tex] - [tex]\frac{2}{15}[/tex]= [tex]\frac{9}{15}[/tex]
