Question

quick ans needed pls ​

Answer 1

Answer:

Step-by-steet denominator =x

so,numerator =x-3

=(x-3)+2/x+5=1/2

x-1/x+5=1/2

=2x-2-x+5

x=7

answer 4/7

 

Answer 2

Answer:

1/4

Step-by-step explanation:

let the denominator be x

then numerator = x-3

so fraction= x-3/x

so, according to question numerator becomes three times and denominator is increased by 20 so new fraction=

3(x-3)/x+20 = 3x-9/x+20

according to question, the resulting fraction= 1/8 so -

3x-9/x+20 = 1/8

= 8(3x-9) = x+20

= 24x-72 = x+20

= 24x-x = 20+72

= 23x = 92

= x = 92/23 = 4

so original fraction = 4-3/4 = 1/4
