Question

the numerator of a fraction is 7 less than its denominator. if 2 is added to the numerator than then the fraction becomes 2/3find the fraction .​

Answer 1

Step-by-step explanation:

denominator is x

so atq numerator =x-7

new fraction=(x-7)+2/x

therefore, x-5/x=2/3

on sloving we get x=15

Answer 2

Answer:

8/15 is the fraction

Step-by-step explanation:

Let the numerator be " x "

Let the denominator be " y "

let the fraction be x / y

According to que ;

=> x = y - 7 ________( 1 )

Also ;

=> x + 2 / y = 2 / 3 _______ ( 2)

By putting the value of ( 1 ) in (2)

we get ;

=> y - 7 + 2 / y = 2 / 3

=> y - 5 / y = 2/3

=> 3 ( y - 5 ) = 2 ( y )

=> 3y - 15 = 2y

=> 3y - 2y = 15

=> y = 15________(3)

Now put the value of y in eq (1)

=> x = 15 - 7

=> x = 8

So the fraction becomes 8 / 15...
