Answer 2

Answer:

answer is -23/6

Step-by-step explanation:

lets first add (-2/3and-7/9)

so, here I multiplied -2/3 with 3 to equalise their denominator.

$\frac{ - 2}{3} + \frac{ - 7}{9} \times \frac{ - 2}{3} \times \frac{3}{3} = \frac{ - 6}{9} \\ \frac{ - 6}{9} + \frac{ - 7}{9} = \frac{-13}{9}$

now, add the fraction (8/3and-5/18),

$\frac{8}{3} + \frac{ - 5}{18} \\ \frac{8}{3} \times \frac{6}{6} = \frac{48}{18} \\ \frac{48}{18} + \frac{ - 5}{18} = \frac{43}{18}$

now, subtract both the sums,

(-13/9) - (43/18) = -23/6

the answer came 2/3 , as I shortened it as,

6 × 2 = 12 and 6 × 3 = 18.

hope this answer helps you.
