Answer 1

Answer:

given-

Numerator + Denominator=20

Denominator×1=1/2 then denominator me 1 he (1/2 ke denominatir me 2 he matlab denominator×1=2,hence 2×1=2 denominator is 2.

now,it is said that numerator+2(denominator)=20,hence numerator=20-2=18

numerator=18 Denominator=2

you understood????

Answer 2

Answer:

7/13

Step-by-step explanation:

let the numerator be x and denominator be y

x+y = 20

= x = 20-y

and if the denominator multiplied by one the fraction become 1/2

=x/y * 1 = 1/2

2 x = y * 1

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

2(20-y) = y*1

40-2y = y * 1

40=3y

= y =13

x= 13-20

x=7
