Question

the denominator of a rational number is greather than its numerator by 3 is subtracted from the numerator and 2 is added to its denominator the new number becomes 1/5 find the original number
​

Answer 1

Answer:

4/7

Step-by-step explanation:

Given :

numerator= x

denominator= 3+x

new number= 1/5

new numerator = x-3

new denominator= 3+x+2

To find:

old number

Solution:

x-3=1

x=1+3

=4

old numerator= x = 4

old denominator= 3+x = 3+4

                           = 7

therefore, new number = 4/7

Answer 2
