It is given that
For chocolate chips, she has = [tex]\dfrac{11}{4}[/tex] pounds
For walnuts, she has = [tex]\dfrac{3}{4}[/tex] pounds
For raisins, she has= 12 ounces
We know that,
[tex]\rm 1 \ pound = 16 \ ounces[/tex]
[tex]\rm For \ chocolate \ chips, she\ has = \dfrac{11}{4} \times 16 }=44 \ ounces[/tex]
[tex]\rm For \ walnuts,\ she\ has = \dfrac{3}{4} \times 16 }=12\ ounces[/tex]
[tex]\rm For\ raisins, she \ has= 12\ ounces[/tex]
