Question

simplify 2/3+-3/5+1/6+-8/15​

Answer 1

$\frac{2}{3} + \frac{ - 3}{5} + \frac{1}{6} + \frac{ - 8}{15} \\ = \frac{20 - 18 + 5 - 16}{30} \\ = \frac{ - 9}{30} \\ = \frac{ - 3}{10}$

Answer 2

Step-by-step explanation:

→ $\dfrac{2}{3}$ + $\dfrac{(-3)}{5}$ + $\dfrac{1}{6}$ + $\dfrac{(-8)}{15}$

♦ LCM of 3, 5, 6 and 15 is $\bold{30}$

→$\dfrac{2 \times10+(-3) \times6+1 \times5 +(-8) \times2}{30}$

→$\dfrac{20-18+5-16}{30}$

→$\dfrac{25-34}{30}$

→$\dfrac{(-9)}{30}$

→$\dfrac{(-3)}{10}$
