a day =24hrs so 10 days=240hrs
20hrs/240hrs ×100%to get the percentage
20/240×100%=8 1/3
Answer: 8.3%
Step-by-step explanation: There are 24 hours a day, so there are 240 hours in 10 days. Then, 240 hours will represent 100% of the total amount of hours. In comparison, 20 hours will represent 8.3% of 240 hours. Therefore, 20 hours will represent 8.3% of 10 days.
