(1/8 + 3/12) x (1 1/6-1/2)

1/2

Step-by-step explanation:

(1/8+3/12)×(11/6-1/2)

Using bodmas

Deal with the bracket first and it should start with the addition

1/8+3/12

Lcm of the two is 96

12+24/96

=36/96

Then move to the next bracket

11/6-1/2

Lcm is 6

11-3/6

=8/6

Bring the two answers together

36/96×8/6

=1/2

4n - 2

Step-by-step explanation:

Greater = 2n

Smaller = 2n - 2

Sum = 2n + (2n - 2)

Sum = 2n + 2n - 2

Sum = 4n - 2
