Two kinds of fish can be found in a small tank that is 5 1/7 feet long. The blue fish is 2 /15 feet long and the orange fish is 7/10 feet long. How much longer is the orange fish?

17/30 feet
Explanation:
Blue fish: 2/15 feet long
Orange fish: 7/10 feet long

Subtract the orange fish’s length by the blue fish’s:
7/10 - 2/15
Find LCD- 30
Multiply both denominators of each fraction by a number that makes both 30 (whatever that number is multiply that also to both nunerators):
7 • 3 / 10 • 3 = 21/30
2 • 2 / 15 • 2 = 4/30

SUBTRACT:
21/30 - 4/30 = 17/30
FINAL ANSWER: the orange fish is 17/30 feet longer than the blue fish.
