3/4+ (1/3 divided by 1/6) - (- 1/2)

3 1/4

Step-by-step explanation:

3/4 + (1/3 divided by 1/6) - (- 1/2)

first calculate between the brackets.

(1/3) / (1/6)

Division is the inverse of multiplying.

(1/3) * (6/1)

multiply both numerators and multiply both denominators

1*6 / 3*1 = 6/3 = 2

3/4 + (2) - (- 1/2)

make all denominators into 4

3/4 + (8/4) - (- 2/4)

- ( - = plus

3/4 + (8/4) + 2/4

3/4 + 8/4 + 2/4

add all numerators since the denominators are all the same.

( 3 + 8 + 2 ) / 4

13/4

3 1/4
