The correct answers are A C and B
Total number of students in the class = 36
Number of students wearing blue shirts = (1/6) * 36
= 36/6
= 6
Number of students wearing white shirts = (2/3) * 36
= 2 * 12
= 24
Then
Number of students not wearing blue or white shirts in the class = 36 - (6 + 24)
= 36 - 30
= 6
So 6 students in the class are wearing a shirt other than a blue or a white shirt. I hope the procedure is clear enough for you to understand.
Given parameters:
Fraction given to charity = 
Fraction given to wife = 
Unknown:
Fraction given to son and daughter =?
Solution:
Let the total property = x
Fraction given to charity = 
Fraction given to wife =
The remaining was given to son and daughter = F
So;
Total property = fraction given to charity + fraction given to wife + fraction given to son and daughter
x = 
F = x - (
)
F = 0
The son and daughter will not inherit anything
Product means to multiple 12y
increase that by 11 so +11
awnser: 12y+11
