What you have to do is subtract 3 2/15 from 7 5/9. You can also use decimals but that doesn't work all the time since the are infinite numbers (you will see what I mean later on) So what you can do is find the improper fraction of each one, and subtract it from each other. It would be 68/9 - 47/15, which would give you a total of 4 19/45. YOU'RE WELCOME :)
The answer would be 30.0385
Answer:
The percentage of the guests at this hotel called for room service yesterday is 40%
Step-by-step explanation:
We are given
total number of guests called for room services =170
total number of guests did not called for room services =255

percentage of the guests at this hotel called for room service yesterday is
%
So,
The percentage of the guests at this hotel called for room service yesterday is 40%
