Final answer:
Daisy has 5 1/2 pounds of chocolate and uses 4/5 of it, which is 4.4 pounds, to bake brownies.
Step-by-step explanation:
The student has 5 1/2 pounds of chocolate and uses 4/5 of it to bake brownies. To find out how much chocolate she uses to bake the brownies, you must multiply the total amount of chocolate by the fraction used for baking.
First, convert the mixed number to an improper fraction:
5 1/2 = (5 × 2 + 1)/2 = 11/2 pounds of chocolate
Next, multiply the total chocolate by the fraction used for the brownies:
(11/2) × (4/5) = (11 × 4)/(2 × 5) = 44/10 = 4.4 pounds
Daisy uses 4.4 pounds of chocolate to bake brownies.
