the denominator of a fraction is 4 more than its numerator. If the fraction equals 1/3, what is the fraction?

Answer 1

Based on the information provided, lets set up an equation for the problem like this:

x 1

--------- = ---------

x + 4 3

Next, let's solve for X by cross multiplying the set of equations and then solving for X like this:

x * 3 = 1 * (x + 4)

3x = x + 4

2x = 4

x = 2

Let's check our work:

(2) 1

----------- = ---------

(2) + 4 3

2 1

------- = -------

6 3

2 / 2 = 1 1

-- = -- CORRECT

6 / 2 = 3 3

Answer 2

Call the numerator x. Then the denominator is x+4

Therefore x/x+4 = 1/3

3x=x+4

2x=4

x=2. So fraction is 2/6

Answer 3

(x) /((x+4) =1/3. This is a simple problem x= unknown number. x+4. is the denominator

Cross multiplying we get. 3x. = x+4

subtracting like terms we get. 3x- x =4. or 2x. = 4. ,so x = 4/2. =2

Substitute this value of x=2 in the original expression I get : (2) /(2+4). =1/3

2/(6) = 1/3 therefore the fraction is 2/6.
