EASY BRAINLESS...

seventy percent of the fish in an aquarium are salmon. if there are a total of 450 fish in the aquarium, how many salmon are there? how many fish are not salmon​

Answer 1

There are 315 salmon and 135 fish that aren't salmon.

Explanation:

The number of salmon in the aquarium would be 70% of the 450 fish, so to find the number you multiply .7 by 450:

450 × .7 = 315

So, there are 315 salmon. To find how many fish are not salmon, you would subtract 315 from 450:

450 - 315 = 135

So, 135 of the fish are not salmon.
