18 points were scored by one figure skating pair and that was 40% of their final score. what was the final score for that pair of figure skaters.

18 points scored for a pair was 40 % of the final score
then final score is 100%
therefore if 40 % accounts for 18 points 
                 100 % = 18 / 40% *100%
                            = 45 points is the final score 
if we back calculate = 18 /45 *100 = 40%
Therefore the final score is 45 points

I’m not sure i’m sorry
