Answer:
The number is 12. 
Step-by-step explanation:
 Given: 
We need to find a number multiply to each term to get rid of fraction. 
We will find LCD of denominator. 
First we see the numbers at denominator 
Denominators are 4,3,2 
Now, we will find the LCD of 2,3, and 4 
Factor of 2: 2x1 
Factor of 3: 3x1 
Factor of 4: 2x2x1 
LCD = 2x2x3 = 12 
If we multiply by 12 to each term to eliminate the fraction. 
Simplest equation: 


Hence, The number is 12.
