<span>Fractions are numbers which can be represented in the form p/q, where p and q are WHOLE NUMBERS and q is not zero
Rational numbers are numbers which can be represented in the form p/q where p and q are INTEGERS and q is not zero
So your saying " all rational numbers are all numbers that can be represented as a fraction." is wrong.......
all fractions are rational numbers but NOT ALL rational numbers are fractions..</span>
        
             
        
        
        
Hey ! 
I am going to explain what I did to get the answer...
I multiplied $29,160 by 30 = $874,800
Then I multiplied $84,460 by 30 = $2,533,800 
Then I subtracted the results = a difference of $1,659,000
So the answer to your question is, $1,659,000 is the difference. 
I hope I was able to help you out :D <span />
        
                    
             
        
        
        
I think the answer is D. The other answers are unreasonable. Wyatt would not get the promotion and just because Tammy's lowest value is bigger than Wyatt's doesn't mean that Tammy gets the promotion. The only reasonable answer is D.
        
             
        
        
        
Let "x" be a substitute for "a number"
1/3(x)=x-12    Multiply by 3
x=3x-36         Get n onto the same side of the equation
2x=36            Divide by 2
x=18
That's your answer.
