Paul makes green paint. the ratio of yellow to blue is 2: 3. if he uses 1/5 ounce of yellow. how much blue should he use?

A. 3/10

Step-by-step explanation:

So the ratio is saying 2 units to 3 units.  What represents 1 unit when 1/5 is two units?  We cut it in half which is 1/10.

Now we have 1 unit so we can easily find three by multiplying by three, or even just adding three together.  So that's 3/10.
