Answer 1

Answer:

=2/3+(-7/11)+(-7/4)

=2/3-7/11-7/4

LCM of 3, 11 & 4=132

=2/3-7/11-7/4

=88-84-231/132

= -227/132

Answer 2

Step-by-step explanation:

$\frac{(2 \times 11 \times 4) + ( - 7 \times 3 \times 4) + ( - 7 \times 3 \times 11)}{3 \times 11 \times 4}$

$\frac{88 - 84 - 231}{132}$

$\frac{ - 227}{132}$
