Final answer:
Kate averaged 2 miles per week this month, after running 75% less than the previous month where she averaged 8 miles per week.
Step-by-step explanation:
A student is asking how much Kate averaged in her running this month if she averaged 8 miles per week last month and ran 75% less this month. To calculate Kate’s average this month, we must find 75% of 8 miles and subtract that from the original 8 miles. This is how you calculate a percentage decrease.
- Calculate 75% of 8 miles: (0.75) × 8 miles = 6 miles.
- Subtract the decrease from the original amount: 8 miles - 6 miles = 2 miles.
Therefore, Kate averaged 2 miles per week this month.
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. The percent symbol, %, or the abbreviation "pct" are frequently used to indicate percentages. The term "percent" derives from "percent," a shortened form of "per centum," which meaning per hundred.
The required formula is:
percentage (%) = Change/total * 100
Percentage Decrease =25%
Percentage Decrease=52%
Percentage Decrease =16.67%
We calculated the percentage decrease using the above-mentioned formula.
