Answer:

The rational number is \frac{8}{13}

Step-by-step explanation:

Let x be the numerator and x + 5 be the denominator.

\frac{(x)+7}{(x+5)-4} = \frac{5}{3}

⇒ x + 7 = \frac{5}{3} ×\frac{(x+5)-  4}{1}

⇒ x + 7 = \frac{5x + 25 - 20 }{3}

⇒ x + 7 = \frac{5x + 5}{3}

⇒ 3(x + 7) = 5x + 5

⇒ 3x + 21 = 5x + 5

⇒ 5x - 3x = 21 - 5

⇒ 2x = 16

⇒ x = 8

Thus, the numerator is 8 and the denominator is 13. The rational number is \frac{8}{13}

I hope this helps!!
