Question

the numerator of a fraction is 1 less than twice the dinomenator .If both the denominator and numerator increased by 1,the fraction becomes ½.what is the fraction? ​

Answer 1

Answer: $\frac{\frac{-1}{3} }{\frac{1}{3} }$

Step-by-step explanation:$\frac{2x-1}{x}$

Let the denominator of the fraction be x:

the fraction in terms of x is $\frac{2x-1}{x}$

$\frac{(2x-1)+1}{x+1} =\frac{1}{2}$

$\frac{2x}{x+1} =\frac{1}{2}$

2(2x)=x+1

4x=x+1

3x=1

x=$\frac{1}{3}$

Plug into $\frac{2x-1}{x}$:

$\frac{(2(\frac{1}{3} )-1)}{\frac{1}{3} }$

$\frac{\frac{-1}{3} }{\frac{1}{3} }$
