Question

jack popped some popcorn, but 3 of the 150 did not pop. Determine whether or not each popcorn snack below has the same ratio of unpopped to total kernals as Jack's popcorn

Answer 1

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 = $\frac{3}{150}$

                                                   = $\frac{1}{50}$

                                                  = 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  = $\frac{2}{75}$

                                                       = 2 : 75  This is not a match

b. 2 unpopped out of 200 kernels = $\frac{4}{200}$

                                                         = $\frac{1}{50}$

                                                         = 1 : 50   This is same

c. 1 unpopped out of 50 kernels = $\frac{1}{50}$

                                                     = 1 : 50 This is also same

So b and c has the same ratio of unpopped to total kernels as Jack's popcorn.

Answer 2

4:200 and 1:50 are the same and 2:75 is different
