Answer:
the number = 8/5 or 1 3/5 or 1.6
Step-by-step explanation:
n = the number
5/2n - 11 = 4
5/2n - 11 + 11 = 5 / 2n
5/2n = 4
5/2n / 5/2 = n
4 / 5/2 = 8/5

Jim's claim is correct
Step-by-step explanation:
Total survey=100 people
Morning exercise=35 people
Afternoon exercise=45 people
Night exercise=20 people
Morning exercise : Total survey
=35 : 100
Afternoon exercise : Total survey
=45 : 100
Night exercise : Total survey
=20 : 100
Jim's claim is correct because in finding the ratio, one has to relate it with the total people involved in the survey.
Tara's claim however seems to relate one variable with two other variables
Example:
35 : 55
Morning exercise : (morning exercise + night exercise)
35 : (35+20)
35 : 55
