Answer 1

EXPLANATION.

⇒ (-3/5) - (-2/15).

As we know that,

We can write equation as,

⇒ (-3/5) + (2/15).

Taking L.C.M in this equation, we get.

⇒ (-9 + 2)/15.

⇒ -7/15.

Option [C] is correct answer.

Answer 2

$\frac{ - 3}{5} - (\frac{ - 2}{15}) \\ lcm = 15 \\ = \frac{ - 3 \times 3}{5 \times 3} - (\frac{ - 2 \times 1}{15 \times 1} )$

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

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

so Option C is the right answer
