8/12=2/3=66.667%
(2/3)*126=84 people were happy
126-84=42 people were not happy

You could solve this using a proportion or just by common sense. 

Proportion: 8/12 = x/126

Cross multiply: 12x = 1008

1008/12 = 84

Or the common sense route is just dividing 12 by 8 then multiplying the answer by 126. Either way, you get the same answer. Hope this helps! :)

The sum of three consecutive odd numbers is 93. What is the smallest of three numbers ?
Julli [10]

Answer:

Step-by-step explanation: it doesn't matter if it says even or odd it's the same formula

Because think if you start with 1 to get 3 you add 2

If you start with 2 to get the next even number you add 2

So it's X+ (X+2)+ (X+4)=93

X is the first # X+2 is the next # X+4 is the 3rd number if you want to check add the numbers to make sure they add up to 93

The smallest of course is X
