If 2 is added to both the numerator and denominator of a fraction its value becomes half. if two is subtracted from both the numerator and denominator of the same fraction its value becomes 1/3. what is the original fraction"

The original fraction is .

Step-by-step explanation:

Solution,

Let the fraction be''.

Where 'x' is the numerator and 'y' is the denominator.

Now according to question, if 2 is added to both the numerator and denominator the value of the fraction becomes 1/2.

So, framing the above sentence in equation form, we get;

On using cross multiplication method, we get;

Now according to question, if 2 is Subtracted to both the numerator and denominator the value of the fraction becomes 1/3.

So, framing the above sentence in equation form, we get;

On using cross multiplication method, we get;

Now Substituting the equation 1 in equation 1 we get;

Now Substituting the value of x in equation 1 we get;

Hence The original fraction is .

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
