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
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.
