Answer:</u></h2>
55% of the fish tank is <u>44 gallons.</u>
<h2><u>
Step-by-step explanation:</u></h2>
To solve this, you turn the 55% into a decimal, by dividing it by 100.
55 ÷ 100 = 0.55
You then <u>multiply</u> the whole capacity (80) by 0.55
80 x 0.55 = <u>44 gallons</u>
13 hours
200 divided by 15 = 13.33333333333333
So since this a long number I have to round.
