Answer: 5%
Step-by-step explanation:
First and foremost, we need to know that 60 minutes = 1 hour. Therefore,
7 hours = 60 × 7 = 420 minutes.
Number of minutes awake = 21 minutes
Number of minutes supposed to be asleep = 7 hours = 420 minutes
The percentage of the seven hours that Frank was awake during the night will be:
= 21/420 × 100
= 1/20 × 100.
= 5%
Answer:
The answer to your question is 43.7 g of chocolate
Step-by-step explanation:
Data
56% cocoa
mass of a chocolate bar = 78 g
Process
To solve this problem, use proportions and cross multiplication, consider the mass of the bar is 100%.
78 g of chocolate ------------------- 100%
x ------------------ 56%
x = (56 x 78) / 100
x = 4368/100
x = 43.68 g
-Round to the nearest tenth
Mass of the chocolate = 43.7 g
