Answer 1

Its B because in other word its 4.25-2.75=1.5

Answer 2

Answer:  The correct option is (B) $1\dfrac{1}{2}.$

Step-by-step explanation:  Given that Alice had $4\dfrac{1}{4}$ pounds of walnuts at the beginning of the week. At the end of the week, she had $2\dfrac{3}{4}$ pounds.

We are to find the quantity of walnuts that she had used.

We have

The quantity of walnuts that Alice has is

$q_1=4\dfrac{1}{4}=\dfrac{17}{4}~\textup{pounds}$

and the quantity of walnut that she had at the end of the week is

$q_2=2\dfrac{3}{4}=\dfrac{11}{4}~\textup{pounds}.$

Therefore, the quantity of walnut that she has used is given by

$Q=q_1-q_2=\dfrac{17}{4}-\dfrac{11}{4}=\dfrac{6}{4}=\dfrac{3}{2}=1\dfrac{1}{2}.$

Thus, the required quantity of walnut that she has used is $1\dfrac{1}{2}~\textup{pounds}.$

Option (B) is CORRECT.
