Set this up as a proportion with seeds on top and plants on bottom. Ours will look like this:

. Cross multiply to get 12x=1092. Divide to get that the number of plants to expect from 156 seeds is 91, choice B from above.
.1515/1 1.515/10 15.15/100 151.5/1000 1515/10000
multiply the numerator and the denominator by 10
your answer is 1515/10000
simplified is 303/2000
Use 12 to divide evenly among 3 sets. it will be 4 each set. 12 is negative, and you are dividing by a positive, so the answer will be negative (-4).
Isnt the first one zero becuse the number between -1 and 1 coupd only be zero
