Answer:

The required fraction is F=\frac{5}{7}

Step-by-step explanation:

Given : The sum of the numerator and denominator of a fraction is 12. If the denominator is increased by 3, the fraction becomes 1/2.

To find : What is the fraction?

Solution : Let the fraction is F=\frac{x}{y}

→ The sum of the numerator and denominator of a fraction is 12.

x+y=12

\Rightarrow x=12-y .........[1]

→ If the denominator is increased by 3, the fraction becomes 1/2.

\frac{x}{y+3}=\frac{1}{2}

\Rightarrow 2x=y+3 .........[2]

Put the value of x from [1] in [2]

2(12-y)=y+3

\Rightarrow 24-2y=y+3

\Rightarrow 3y=21

\Rightarrow y=7

Put back the value of y in [1]

x=12-7

\Rightarrow x=5

Therefore, The required fraction is 5/7.
