What score will she get? Set up a proportion to find out.

Nancy shot a 30 on 6 holes of golf, at this rate what can she expect to score if she plays all 18 holes?

---

Set up a proportion.

x = score on 18 holes

30/6 = x/18
5 = x/18  {reduced 30/6}
x = 90  {multiplied each side by 18}

She should expect to score 90 on 18 holes.
