answer:
To find the percent of decrease from 10 to 8, we can use the following formula:
Percent decrease = (Original value - New value) / Original value * 100%
Let's plug in the values and calculate the percent of decrease:
Original value = 10
New value = 8
Percent decrease = (10 - 8) / 10 * 100%
Simplifying the expression:
Percent decrease = 2 / 10 * 100%
Percent decrease = 0.2 * 100%
Percent decrease = 20%
Therefore, the percent of decrease from 10 to 8 is 20%. This means that the value decreased by 20% from the original value of 10 to the new value of 8.
