Final answer:
To find out how many miles Demitri hiked on Thursday, we calculate 75% of the distance he hiked on Wednesday by multiplying it by 0.75.
Step-by-step explanation:
To find out how many miles Demitri hiked on Thursday, we need to calculate 75% of the distance he hiked on Wednesday. We can do this by multiplying the distance he hiked on Wednesday by 0.75, or by subtracting 25% from 100%.
First, we need to convert the 12 miles into a decimal by dividing by 100: 12 / 100 = 0.12 miles.
Now, we can find out how many miles Demitri hiked on Thursday by multiplying 0.12 miles by 0.75: 0.12 * 0.75 = 0.09 miles.
Therefore, Demitri hiked 0.09 miles on Thursday.
The question is asking how many miles Demitri hiked on Thursday if he hikes 25% less than the 12 miles he hiked on Wednesday. To find the answer, we need to calculate 25% of 12 miles and then subtract that from 12 miles.
First, find 25% of 12 miles:
25% as a decimal is 0.25.
Multiply 12 miles by 0.25 to find the decrease in miles.
12 miles × 0.25 = 3 miles.
Next, subtract the decrease from the original distance:
12 miles - 3 miles = 9 miles.
So, Demitri hiked 9 miles on Thursday.
