Answer 2

Answer :

• Other number is 16/85

Given :

• Sum of two rational number is 10/17
• One of them is 2/5

To find :

• Other number

Solution :

• Let the other rational number be y
• x = 2/5
• y = ?
• z = 10/17

We know that

• x + y = z

↦ x + y = z

↦ 2/5 + y = 10/17

↦ y = 10/17 - 2/5

↦ y = 10 × 5 / 17 × 5 - 2 × 17 / 5 × 17

↦ by taking lcm

↦ y = 50/85 - 34/85

↦ y = 50 - 43 / 85

↦ y = 16/85

Hence,

Other number is 16/25.
