Answer 1

Answer:

5/7

Step-by-step explanation:

Answer

Let the numerator be x

so the denomibator will be 12-x

sum ____x+12-x=12

A.T.Q

x/12-x+3=1/2 linear equation

=2×x=1×(12-x+3) cross multiplication

=2x=12-x+3

=2x+x=12+3

=3x=15

=x=15/3

x=5

so the numerator is 5 (numerator was taken x)

denominator is 12-5=7 (denominator was taken12-x)

the fraction is =5/7
