18. -1/2
Step-by-step explanation:
18. first find the LCD. the LCD is 6 now 6 is our new denominator.
remove the negative line so that it is not confusing
6 divided by 3= 2
2 x 2=4 so the first fraction is 4/6
6 divided by 2=3
3 x 1=3 the sec fraction is 3/6
now bring the numerator back so it will be -4/6 and -3/6
since it has negavite wichmean the lower the number the higher the -3/6 has the lower numerator so the answer is -1/2
