Question

Alice had 4 1/4 pounds of walnuts at the beginning of the week. At the end of the week, she had 2 3/4 pounds. How much has she used?

A. 1 3/4
B. 1 1/2
C. 2 1/2
D. 1 1/4

Answer 1

I think the correct answer from the choices listed above is option B. Alice had used 3/2 or 1 1/2 pounds of the walnuts she had. It is calculated by getting the difference of the amount in the beginning and the amount left at the end of week. Hope this answers the question.

Answer 2

Step
`1`

Convert mixed numbers to improper fractions

we know that

`4(1)/(4)=(4*4+1)/(4)=(17)/(4)`

`2(3)/(4)=(2*4+3)/(4)=(11)/(4)`

Step
`2`

Find the difference of the numbers

`(17)/(4)-(11)/(4)=(6)/(4)=(3)/(2)`

Step
`3`

Convert improper fraction to mixed number

`(3)/(2)=1.5=1+0.5=1+(1)/(2) =1(1)/(2)`

therefore

the answer is the option B

`1(1)/(2)`
