Question

The denominator of a rational no. is greater than its numerator by 3. If three is subtracted from the numerator and 2 is added to its denominator the new no. is 1/5. Find the original no.

Answer 1

Answer:

let

Denominator = x

and numerator = y

and ans is

y= 5

x= 8

Step-by-step explanation:

a/p

$y + 3 = x$

$y - 3 \div x + 2 = 1 \div 5 \:$

5y-15 = x+2

5y-15 -2 = x

5y- 17 = y+3

5y - y = 17 + 3

4y = 20

y = 5

putting value of y in 5

x= 5
