Question

Shelby bought a 2-ounce tube of blue paint. She used 2/3 ounce to paint the water, 3/5 ounce to paint the sky, and some to paint a flag. After that, she has 2/15 ounce left. How much paint did Shelby use to paint her flag?

Answer 1

Answer:

The amount of ounce used for paint is $\frac{9}{15} ounce$  

Step-by-step explanation:

used amount for water is $\frac{2}{3}$ ounce.

used amount for sky is $\frac{3}{5}$ ounce.

thus, the total amount used is $\frac{2}{3}$ +  $\frac{3}{5}$

= $\frac{19}{15}$

Thus the total unused amount is 2 - $\frac{19}{15}$ = $\frac{11}{15}$ .

But the remaining amount is $\frac{2}{15}$.

Thus used amount for flag is $\frac{11}{15}$ - $\frac{2}{15}$

= $\frac{9}{15}$
