Tina is tossing bean bags at a target. She hit the target on 3 out of her last 15 tries. Considering this data, how many hits would you expect Tina to get during her next 10 tosses?

We are given 3 out of 15, the best is to convert into a percent, is our fraction, now divide the numerator by the denominator 3÷15=.0.20. Now bump it up two digits, 20%. Now 20% of 15 is 3, we need to find 20% of 10, if 20% is 20 from 100, then 2 must be 20% of 10.

And your answer is 2 out of 10 tosses.
