Answer 1

Given

• Sum of two rational number = -7
• One of the number is -15/19

To find

• Another number

Solution

★ Let the another be x

→ sum of two rational number = -7

→ -15/19 + x = - 7

→ x = 15/19 - 7

→ x = 15 - 133/19

→ x = -118/19

Hence,

• Another number is -118/19

NOTE : A rational number is a number that can be expressed in fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

Answer 2

Answer:

x + -15/19 = -7

x = (-7) - (-15/19)

x = -621/100
