Question

Badnaam need of rational number greater than the numerator of by 10 is increased by 1 and the denominator is decreased by 1 then the new expression for the denominator will be​

Answer 1

b-10=a

b=a+10

a+1/b-1=x/y

a+1/a+10-1=x/y

a+1/a+9=x/y

ya+y=ax+9x

y-9x=ax-ya

a(x-y)=y-9x

a=y-9x/x-y

a+10=b

y-9x/x-y+10=b

y-9x+10x-10y/x-y=b

X-9y/x-y=b

a/b=(y-9x/x-y)/(x-9y/x-y)

a/b=y-9x/x-9y
