A fish tank that holds 80 gallons of water is 55% full b. How many gallons are in the tank now? How many more gallons are needed to fill the tank?

36 gallons

Step-by-step explanation:

Step 1: Find 55% of 80.

0.55*80=44

Step 2: 80-44=36

Step 3: 36 gallons

a. How many gallons are in the tank now?

44 gallons of water are in the tank now.

b. How many more gallons are needed to fill the tank?

36 gallons

Step-by-step explanation:

In the above Question, A fish tank can hold 80 gallons of water.

The fish tank is 55% full

a. How many gallons are in the tank now?

The fish tank is 55% full now

55% = 55: 100

Therefore,

55% of 80 gallons is what we have in the fish tank now

= (55 : 100) * 80

= 44 gallons

Therefore we have 44 gallons of water in the tank now.

b. How many more gallons are needed to fill the tank?

Formula is given as

Total number of gallons of water required to fill the tank - number of gallons of water in the tank now.

Total number of gallons of water required to fill the tank = 80 gallons.

Number of gallons of water in the tank now = 44 gallons

Number of gallons required to fill the tank = 80 gallons - 44 gallons

= 36 gallons.

Therefore the number of gallons needed to fill the tank is 36 gallons.
