Answer:
1/3
Explanation:
Multiply left to right, so you start with -1/6*4/7=-2/21
Then you apply the fraction rule so -1/6*4
and 4 can be expressed by 4/1 so -1/6*4/1=-2/3
Then after solving you will get -4/6
then you factor 4=2*2 what will be -2*2/6
Then you cancel the common factors what are 2
so you bring back the 7 so -2/3/7 and 7 can be expressed as 7/1 and then you apply the fraction rule and flip it to 1/7 what will be solved as -2/21
so then it will be -2/21+1/2-1/14-3/7*1/6
Then you will have to solve -3/7*1/6 what is 1/14
so -2/21+1/2-1/14=1/3 final equation
