Answer 1

Answer: A)
`(3)/(4)`

B) 75%

C) She bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.

Explanation:

Given: The ratio of the number of sesame bagels to the number of plain bagels is 1:3.

Let the number of sesame bagels be x and the number of plain bagels be 3x.

Then total bagels=x+3x=4x

A) The fraction of bagels are plain
`=(3x)/(4x)=(3)/(4)`

B) The percent of bagels are plain
`=(3)/(4)*100=75\%`

C) If ill bought 2 dozen bagels, the number of plain bagels

The number of sesame bagels
`=(x)/(4x)*2\text{ dozen}=(1)/(2)\text{ dozen}=0.5\text{ dozen}`

Hence, she bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.

Answer 2

a.) 3/4 are plain b.) 75% are plain c.) 18 are plain and 6 are sesame. 2 dozen bagels is the same as 24 bagels. Since there are 4 total parts, you have to divide the number of bagels into 4 equal parts [24 / 4]. Since each part is 6 bagels, multiply 6 by 3 since the ratio of plain to sesame is 3:1. Yours should get 18 plain bagels. Then, since 3 of the 4 parts are plain, and each part is 6 bagels, there are 6 sesame bagels.
