Answer 2

$\huge\mathfrak{Answer:}$

Rational numbers:

• Rational numbers are the numbers that can be written in the form of p/q where p and q are integers and q is not equal to zero.
• Example: 2/3, 4/5, 1/7 etc.

Given:

• We have been given two rational numbers 3/5 and 2/5.

To Find:

• We need to find a number that must be added to 3/5 to get 2/5.

Solution:

Let the number that must be added to 3/5 to get 2/5 be x.

According to the question, we have

$\sf{ \dfrac{3}{5} + x = \dfrac{2}{5} }$

$\implies\sf{ x = \dfrac{2}{5} - \dfrac{3}{5} }$

$\implies\sf{ x = \dfrac{(2 - 3)}{5} }$

$\implies\sf{ x = \dfrac{ - 1}{ \: 5} }$

Verification:

$\implies\sf{ \dfrac{3}{5} - \dfrac{1}{5} }$

$\implies\sf{ \dfrac{(3 - 1)}{5} }$

$\implies\sf{ \dfrac{2}{5} }$

Hence, the required number is -1/5.
