I could be wrong, but I believe the answer is 90:380
There are 769 people surveyed in total, 240 and 340 of them are separate from the number of people who preferred peas,
240 + 340 is 580
In order to find put how many people preferred peas, subtract the number of people separated from the people who preferred peas and the total number of people surveyed:
760 - 580, which is 180
That would mean the ratio of people who preferred peas to the total amount of people surveyed would be 180:760 unsimplified
In order to simplify the ratio, we must find the highest common factor, the biggest possible number that these numbers both divide into evenly:
180 and 760 both divide evenly into 2, so the ratio simplified would be 90:380
Please let me know if this answer was wrong!
