Answer 1

Given :

• Sum of two rational number is 5.
• One number is -3/4

To Find :

• The second number.

Solution :

Let's assume,

• The second number be x

According to the Question :

• Sum of two rational number = 5
• -3/4 + x = 5
• x = 5 + 4/3
• x = 5 × 3 + 4/3
• x = 15 + 4/3
• x = 19/3

Verification :

• Sum of two rational number = 5
• -3/4 + 19/3
• -3 × 3/4 × 3 + 19 × 4/3 × 4
• -9/12 + 76/12
• -9 + 76/12
• 67/12
• 5.58 [approx]

Therefore :

• The second number is 19/3
