Math Problem Statement

The denominator of additional number is greater than its numerator by 6 if we subtract new number number become 1​ by 4 the find original number

Solution

Let's denote the original number as xx+6\frac{x}{x+6}, where:

  • The numerator is xx,
  • The denominator is 6 more than the numerator, so it's x+6x + 6.

According to the problem, subtracting the number from 11 gives 14\frac{1}{4}, so we can set up the equation:

1xx+6=141 - \frac{x}{x+6} = \frac{1}{4}

Step 1: Solve for xx+6\frac{x}{x+6}

Subtract xx+6\frac{x}{x+6} from 1:

(x+6)xx+6=1x+6\frac{(x+6) - x}{x+6} = \frac{1}{x+6}

This simplifies to:

1x+6\frac{1}{x+6}

So, the equation becomes:

1x+6=14\frac{1}{x+6} = \frac{1}{4}

Step 2: Solve for xx

Now, set the denominators equal to each other:

x+6=4x + 6 = 4

Solve for xx:

x=46=2x = 4 - 6 = -2

Step 3: Verify the solution

The original number is 22+6=24=12\frac{-2}{-2 + 6} = \frac{-2}{4} = -\frac{1}{2}.

Let's check if the condition holds: 1(12)=1+12=321 - \left(-\frac{1}{2}\right) = 1 + \frac{1}{2} = \frac{3}{2} And: 3214\frac{3}{2} \neq \frac{1}{4}

It appears there was an error, let me rework the steps and find the correct result.

Reattempt

Let the original number be xx. Then we are told:

1x=141 - x = \frac{1}{4}

So, subtracting xx from 1 gives 14\frac{1}{4}, which leads to:

x=114=4414=34x = 1 - \frac{1}{4} = \frac{4}{4} - \frac{1}{4} = \frac{3}{4}

Thus, the original number is 34\frac{3}{4}.

Would you like more details or clarifications on any step? Here are some related questions for further practice:

  1. If the denominator is 8 more than the numerator, and the difference from 1 is 15\frac{1}{5}, what is the number?
  2. Solve for xx if xx+5=23\frac{x}{x+5} = \frac{2}{3}.
  3. What is the value of xx if the denominator is twice the numerator, and subtracting from 1 results in 16\frac{1}{6}?
  4. Find a fraction where the denominator is 4 more than the numerator and the sum of the fraction and 13\frac{1}{3} is 11.
  5. If subtracting a fraction from 1 gives 27\frac{2}{7}, and the denominator is 5 more than the numerator, what is the fraction?

Tip: Always ensure to verify solutions by substituting the values back into the original problem.
