Understanding:
The total number of students is 40. 8.20% of them were absent, which means the rest were present, or in other words, (100-8.20)% were present or 91.8%. We can find the actual number of present students by multiplying the percentage of present students by the total number of students.
Solution:
Present Percentage = 91.8% or 
Present Students = 
, since we are dealing with people we have to round it, so the present students are actually 37.
We have to isolate b to be alone.
Soooo first we divide both sides by 6
-81 = b6
÷6 = ÷6 The right side cancels out and gets the b alone. While we solve the right side of the equal sign.
-81 ÷ 6 = -13.5
So this means we isolated b alone!
b = -13.5
Our final answer is..
b = -13.5

Answer: 7/24
Step-by-step explanation:
1/4 + 1/3 + 1/8
They all need a common denominator to be added:
6/24 + 8/24 + 3/24 =
17/24
The remaining number to 24 is the answer (17/24 + 7/24 = 24/24)
