Question

The sum of two rational number is -7/12.if one of them is 13/24, find the other.

Answer 1

Answer:

sum of two rational number =-7/12

one of them=13/24

other =-7/12-13/24=-33/12

Step-by-step explanation:

Answer 2

Other number =

$- 1 \frac{1}{8}$

GIVEN:- Sum of two rational number is -7/12; one of them is 13/24

TO FIND:- other number

SOLUTION:-

• The Sum of two rational numbers means the addition of a rational number to another rational number.

Let the other rational number be x

$x + \frac{13}{24} = \frac{ - 7}{12}$

Shifting from one side to another changes the signs

$x = \frac{ - 7}{12} - \frac{13}{24}$

By taking LCM to make the denominators equal

$x = \frac{ - 7 \times 2}{12 \times 2} - \frac{13 \times 1}{24 \times 1} \\ x = \frac{ - 14}{24} - \frac{13}{24} \\ x = \frac{ - 14 - 13}{24} \\ x = - \frac{27}{24} \\ x = - 1 \frac{3}{24} \\ x = - 1 \frac{1}{8}$

Hence other number = $- 1 \frac{1}{8}$
