Sally buys some fish for her aquarium 6/25 of the fish are clownfish 13/40 of the fish are butterfly fish.the rest of the fish are seahorses what percentage of the fish are seahorses

1 answer

To find the percentage of the fish that are seahorses, we need to subtract the fraction of clownfish and butterfly fish from 1 (since the total percentage should add up to 100%).

The fraction of clownfish is 6/25, and the fraction of butterfly fish is 13/40.
The fraction of seahorses can be calculated as 1 - (6/25 + 13/40).

First, we need to find a common denominator for 25 and 40, which is 200:
(6/25) * (8/8) = 48/200
(13/40) * (5/5) = 65/200

Now subtract the fractions:
1 - (48/200 + 65/200) = 1 - (113/200) = (200/200) - (113/200) = 87/200

To find the percentage, divide the numerator by the denominator and multiply by 100:
(87/200) * 100 = 43.5%

Therefore, approximately 43.5% of the fish in Sally's aquarium are seahorses.
