Question

The denominator of a fraction is greater than its numerator by 12. if the numerator is decrease by 2 and the denominator is increased by 7. ok so tell me kya promise karu ​

Answer 1

Step-by-step explanation:

Let the numerator of the fraction be x. If the numerator is decreased by 2 and the denominator is increased by 7, the new fraction obtained is . ∴ Numerator of the fraction is 23. ∴ Denominator of the fraction is 23 + 12 = 35.

Answer 2

Answer:

Let the numerator of the fraction =x

Then denominator=12+x

So, fraction will be

12+xx

New fraction:

numerator =x-2

denominator=12+x+7

=19+x

So, fraction will be

19+xx−2

19+xx−2=212(x−2)=19+x2x−x=19+4x=23

So, old fraction is

12+2323=3523

and new fraction is,

19+2323−2=4221=21
