Question

the numerator of a fraction is 5 less than the denominator if 5 added to numerator and 2 to the denominator , fraction becomes 4/5 find. the frictional.​

Answer 1

Answer:

3/5

Step-by-step explanation:

Let denominator be =x

Then numerator = x-5 (given in question)

Then 5 is added to numerator = x-5+5= x

and 2 is added to the denominator = x+2

therefore,

x/(x+2)=4/5

5x=4(x+2) (by cross multiplying)

5x=4x+8

5x-4x=x=8

therefore original fraction,

(x-5)/x =(8-5)/8= 3/5
