Q 12) The sum of two rational
numbers is - 3. If one of the numbers
is (-7)/5 , find the other number.
O (-8)/5
O (8)/5
O (-6)/5
O 6/5​

Answer 1

Given :-

• Sum of two rational numbers = -3
• One of the number = -7/5

To find :-

• Other number

Solution :-

★ Let the other number be x

According to the question

→ x + (-7)/5 = -3

→ x = 7/5 - 3

→ x = 7 - 15/5

→ x = -8/5

Hence,

• Other rational number is -8/5

Given:-

• sum of two rational number is (-3)
• one of the numbers is (-7)/5

To find:-

• the other number

Solution:-

According to the Q,

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

$= > \frac{5x - 7}{5} = ( - 3)$

$= > 5x - 7 = ( - 15)$

$= > 5x = ( - 15) + 7$

$= > 5x = ( - 8)$

$= > x = \frac{( - 8)}{5}$

Hence the other number will be (-8)/5
