Question

solve the following ​

Answer 1

Step-by-step explanation:

take the lcm of denominators i.e 12, it becomes

$\frac{4( - 2) + 2(1) + 3(5)}{12}$

$\frac{ - 8 + 2 + 15}{12} \\ \frac{9}{12} \\ \frac{3}{4}$

Answer 2

-2/3 + 1/6 + 5/4

lcm is 12

-2/3 × 4/4 + 1/6 × 2/2 + 5/4 × 3/3

= - 8/12 + 2/12 + 15/12

= 9/12 = 3/4
