Question

What should be added to sum of 2/3 and 3/5 to get -2/15

Answer 1

Step-by-step explanation:

Let the number be x

A/Q,

$x + ( \frac{2}{3} + \frac{3}{5} ) = \frac{ - 2}{15}$

$x + ( \frac{10 + 9}{15} ) = \frac{ - 2}{15}$

$x + ( \frac{19}{15} ) = \frac{ - 2}{15}$

$x = \frac{ - 2}{15} - \frac{19}{15}$

$x = \frac{ - 2 - 19}{15}$

$x = \frac{ - 21}{15}$
