Answer:

Given :-

• The sum of two rational number is 1.
• One of them is - 3/7.

To Find :-

• What is the other number.

Solution :-

Let,

➢ Other Number = x

Given :

• Sum of two rational number = 1
• One of the rational number = - 3/7

According to the question,

↣ - 3/7 + x = 1

↣ x = 1 + 3/7

↣ x = 7 + 3/7

↣ x = 10/7

➲ x = 10/7

∴ The other number is 10/7 .

✰ VERIFICATION ✰

➞ - 3/7 + x = 1

By putting x = 10/7 we get,

➞ - 3/7 + 10/7 = 1

➞ - 3 + 10/7 = 1

➞ 7/7 = 1

➠ 1 = 1

Hence, Verified.
