Answer:
6.25%
Step-by-step explanation:
The win ratio is the percetage of all accepted contracts that the contractor had in the month. The total number of proposals is 16 because each customer received four proporsals and if there are four different costummer, we multiply 4*4=16. To calculate the win ratio we divide the total number of wins, in this case one, over the total number of proporsals
1/16=0.0625*100= 6.25 %
