Step-by-step explanation:

5 is greater than 2 by 3

the sum of 5 and 2 is 7

fraction is 2/5

Answer 2

Step-by-step explanation:

Given:-

denominator of a rational number is greater than its numerator by 3 and sum of these digits is 7.

To find:-

Find the fraction

Solution:-

Let the numerator be X

Then the denominator =

Numerator +3= X+3

Sum of the digits = 7

=>X+X+3 = 7

=>2X+3 = 7

=>2X = 7 -3

=>2X = 4

=>X = 4/2

=> X = 2

The value of X = 2

Numerator = 2

Denominator = X+3 = 2+3 = 5

The rational number = Numerator/ Denominator

=2/5

Answer:-

The required rational number = 2/5

Check:-

Numerator = 2

Denominator =5 = 2+3

Denominator= Numerator+3

Sum of the digits = 2+5 = 7
