A tank having a capacity of 300 gallons is 3/4 full. How many gallons are needed to make it 4/5 full??
(4/5 -3/4) * 300
225
It's 15 you !@#$%^&
just kidding
you are all intelligent
Since the total capacity of tank is 300 gallons:
(3/4)*300 = 225 {gives the amount of water needed to make 3/4th full}
(4/5)*300 = 240 {amt. of water to make 4/5th full}
Gallons needed = 240-225
= 15 gallons
To solve this problem, we need to determine the number of gallons needed to reach 4/5 full from being 3/4 full.
First, let's find out how many gallons are currently in the tank. If the tank is 3/4 full, we can multiply the tank's capacity by 3/4:
300 gallons × 3/4 = 900/4 = 225 gallons.
So, there are currently 225 gallons in the tank.
Now, we need to find out how many gallons are needed to make it 4/5 full. To do this, we subtract the current amount (225 gallons) from the desired amount when the tank is 4/5 full.
The desired amount can be calculated by multiplying the tank's capacity by 4/5:
300 gallons × 4/5 = 1200/5 = 240 gallons.
To find the additional gallons needed, we subtract the current amount from the desired amount:
240 gallons - 225 gallons = 15 gallons.
Therefore, to make the tank 4/5 full from being 3/4 full, we would need an additional 15 gallons.
