Question

the sum of two rational numbers is -7/15. if one of the numbers is -3/10,find the other.​

Answer 1

Answer:

The correct answer is (-1/6).

Step-by-step explanation:

Given, sum of two rational nos.

$= \frac{ - 7}{15}$

One of the rational nos.

$= \frac{ - 3}{10}$

•°• The other rational no.

$= \frac{ - 7}{15} - ( \frac{ - 3}{10} )$

$= \frac{ - 7}{15} + \frac{3}{10}$

$= ( \frac{3 \times 6}{10 \times 6} ) - ( \frac{ 7 \times 4}{15 \times 4} )$

$= \frac{18}{60} - \frac{28}{60}$

$= \frac{1 8 - 28}{60}$

$= \frac{ - 10}{60}$

$= \frac{ - 1}{6}$

Hence, the other rational no. is -1/6.
