Are you asking what are like fractions? If so, like, or alike fractions are two fractions with the same denominator, (the bottom number of the fraction).
For example, 1/10 and 7/10. If that was not what you were asking, please let me know and I'll try my best. Hope this helped you!
To find mean, add all of your given numbers, then divide by how many numbers you have in your data set.
87+93+86+90+84=440
440/5 (There are five numbers in your data set) is 88.
