A marine biologist measured one fish that was 8 1/2 feet long and a second fish that was 6 feet long. How much longer was the first fish? Write your answer as a fraction or as a whole or mixed number.
To find out how much longer the first fish is than the second, we need to subtract the length of the second fish from the length of the first fish.
1. First fish length = 8 1/2 feet
2. Second fish length = 6 feet
Now, let’s convert 8 1/2 feet into an improper fraction for easier calculation:
8 1/2 = 8 + 1/2 = 16/2 + 1/2 = 17/2 feet
Now, we subtract the length of the second fish:
17/2 feet – 6 feet
We can convert 6 feet into a fraction with a denominator of 2:
6 feet = 12/2 feet
Now, we perform the subtraction:
17/2 – 12/2 = (17 – 12)/2 = 5/2 feet
Finally, we can convert 5/2 into a mixed number:
5/2 = 2 1/2 feet
So, the first fish is 2 1/2 feet longer than the second fish.
