Part B
What percent of each order will be size Medium items? QUICK PLS and Exact answer and explain

Answer 1

Explanation:

the question tells us already what ratio to build : "# of medium sized items / total # of items".

now look at the table. in such a case (different to the one with the soccer vs. basketball preferences) all the specific ratios should be equal. this is like a mixing ratio for a certain substance out of a certain list of ingredients. it does not matter how much you produce, but the mix ratio should always be the same.

10 / 40 = 1/4

15 / 60 = 1/4

20 / 80 = 1/4

perfect.

so, the constant ratio is 1:4

it means one out of 4 ordered items has to be medium sized.

what percentage is 1/4 ?

make the division :

1 : 4 = 0.25

10

20

what is 0.25 ?

it is 0.25 when related to 1 indicating the whole.

and when 100(%) indicates the whole ?

then it is 100 times its value = 0.25×100 = 25%

1/4 corresponds to 25%.
