Hello!
First you have to find what percentage prefers oranges with the current data
Add all the numbers up
150 + 220 + 235 + 185 = 790
Divide the amount that preferred oranges by the total amount of people that answered
185 / 790 = 0.23417721519
Since this is a long decimal we can multiply the fraction by the amount we want to know
185 / 790 * 2370 = 555
The answer is 555 people
Hope this helps!
21/52

The number 1.52 can be expressed using this fraction 152/100. This fraction is equal to 38/25 when reduced to lowest terms. This fraction is also equal to 1 13/25 when expressed as a mixed number.
One way you could do this is by dividing 94 by 3 and then 95 by 4. This gives you the KPH (Kilometers per hour) of both trains. The first speed you mentioned, we will call that speed 'A.' The second one will be speed 'B.' Speed A's KPH is 23.75 MPH. Speed B's KPH is 31.333. We can change these into fractions (23 3/4 and 31 1/3.) These fractions could then be set into like terms. (This gives us 285/12 and 376/12) We then add these together. This gives us 661/12. The next thing to do is to convert this back to a decimal form, which gives us 55.0833.... Divide this number by two, and that is your answer. The average speed of the train is 29.04 KPH (This number is rounded to the nearest hundreth- be sure to make a note of that on your answer sheet)
