Answer: -5/4
Step-by-step explanation:
Apply the fraction rule: a/-b = -a/b
-5/6/2/3
-----------------------------------------------------------------------------------------------------------------
Divide fractions: a/b/c/d = a x d/ b x c
-5 x 3 / 6 x 2
-----------------------------------------------------------------------------------------------------------------
Multiply the numbers: 6 x 2 = 12
-5 x 3 / 12
-----------------------------------------------------------------------------------------------------------------
Multiply the numbers: 5 x 3 = 15
-15/12
-----------------------------------------------------------------------------------------------------------------
Cancel the common factor.3
-5/4

I believe you meant to say that if Samantha bought 510 pounds of hamburger, how much will she pay?
Now from the information we already have, we know that 3 pounds of hamburger will cost 6 dollars.
The next thing we need to know is how much one pound of hamburger will cost. This will help us calculate how much the rest will cost.
we now form an equation to assist us.
3 = 6
1= x
(where x represents the unknown price of one pound of hamburger)
Now we must cross-multiply:
3 * x = 6 x 1
3x = 6
x = 6/3
x = 2
therefore one pound of hamburger costs 2 dollars.
Now, If one pound costs 2 dollars, how about 510 pounds?
We simply multiply: 510 x 2 = 1,020
Therefore Samantha will pay 1, 020 dollars for 510 pounds of hamburger.
