Answer:
Step-by-step explanation:
A fraction where the numerator is smaller than the denominator is called proper fraction e.g 2/3,4/7 etc
Answer: 13.6% needed more time but then said no. 25.6% were contacted but said no.
To do this problem, you have to create a tree diagram with all of the possibilities.
The first branch separates with 20% not being contacted and 80% being contacted.
Then, the 80% branch can be broken into 12% saying no and 68% needing more time (multiply by 15% and 85%).
Then, the 68% branch can be broken into 54.4% going and 13.6 not going (multiply by 80% and 20%).
With the tree diagram, just pick the percents that you need.
