3 PART PROBLEM:

Question

Jen bought some sesame bagels and some plain bagels. The ratio of the number of sesame bagels to the number of plain bagels is 1:3.
a)What fraction of the bagels are plain?
b)What percent of the bagels are plain?
c)If Jill bought 2 dozen bagels, how many of each type of bagel did she buy?
Thank you!

Answer 1

The trick is:
Out of every four bagels one is sesame and three are plain
so that
sesame/plain = 1/3

sesame/all = 1/4 = .25 = 25%
plain/all = 3/4 = .75 = 75%

(1/4) 24 = 6 sesame
(3/4) 24 = 18 plain

Answer 2

How did you get the 4!!!!!!!

Answer 3

You add 1 + 3 because that is the total number of bagels that Jen bought.

Answer 4

the awnser is 3/4=0.75=75%
