Answer:
b and c
Step-by-step explanation:
Jack popped some popcorn, but 3 of the 150 did not pop.
the ratio of the jack's popcorn = [tex]\frac{3}{150}[/tex]
= [tex]\frac{1}{50}[/tex]
= 1 : 50
We will go through all the other given ratio to find whether they are same ratio of Jack's or not.
a. 2 unpopped out of 75 kernels = [tex]\frac{2}{75}[/tex]
= 2 : 75 This is not a match
b. 2 unpopped out of 200 kernels = [tex]\frac{4}{200}[/tex]
= [tex]\frac{1}{50}[/tex]
= 1 : 50 This is same
c. 1 unpopped out of 50 kernels = [tex]\frac{1}{50}[/tex]
= 1 : 50 This is also same
So b and c has the same ratio of unpopped to total kernels as Jack's popcorn.
