Question

please tell me the answer in process ​

Answer 1

Answer:

- 3/4

Step-by-step explanation:

$( \frac{3}{4} \times \frac{8}{ - 9} ) - ( \frac{5}{6} + \frac{3}{ - 4} )$

=

$( \frac{2}{ - 3} ) - ( \frac{5}{6} - \frac{3}{4} ) \\ = \frac{3}{4} - \frac{5}{6} - \frac{2}{3}$

taking L.C.M:

2 | 4 — 6 — 3

2 | 2 — 3 —3

3 | 1 —3—3

| 1— 1— 1

2 ×2 ×3 = 12

so,

$\frac{3(3) - 5(2) - 2(4)}{12}$

=

$\frac{9 - 10 - 8}{12}$

= - 9/ 12

= - 3/4
