Question

10) The numerator of a fraction is 5 less than the denominator. If 2 is added 2 points
to both numerator and denominator, it becomes 4/5. Find the original fraction​

Answer 1

Let denominator of the original fraction = x

Then numerator = x – 5

and fraction = (x – 5)/x

According to the condition,

(x – 5 + 3)/(x + 3) = 4/5

⇒ (x – 2)/(x + 3) = 4/5

⇒ 5(x – 2) = 4x + 12

(By cross multiplication)

⇒ 5x – 10 = 4x + 12

⇒ x = 22

∴ Original fraction = (x – 5)/x

= (22 – 5)/22 = 17/22

Answer 2

Answer:

the answer is 18 upon 23

Step-by-step explanation:

at first we let x minus 5 upon x again x - 5 + 2 open x + 2 equals to 4?5 then solve
