Question

44) A swimming pool is filled with 1,000 gallons of water. Then 40% of the water is drained out How many gallons are left?​

Answer 1

Answer:

600 gallons

Step-by-step explanation:

According to the  information provided in the question it is given as

Swimming pool filled with water = 1000 gallons

40% of water is then drained

We need to find how many gallon water left after drain water

As seen it is clearly a question based on percentage so percentage is

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

We need to find  40%of 1000

$=\frac{40}{100} \times 1000$

Converting to the lowest term we get

(As 100 and 1000 both are divisible by 100)

$=10 \times 40\\=400 gallons$

Water left in  pool = Actual water at start -  Water After 40% drained drained

Hence by putting the value we get the water left in swimming pool

$=1000 - 400\\= 600 gallons$

So after drained 40% water  600 gallons water left in swimming pool

Answer 2

Answer:

Hence 600 gallons of water is left in the swimming pool.

Step-by-step explanation:

As per the data provided in the given question

The given data is as follows

A swimming pool is filled with 1000 gallons of water

We have to find how many gallons are left in a swimming pool if 40% of the water is drained out.

Here we have to use the percentage formula,

Given the amount of water is 1000gallons,

Now 40% of water is drained,

$=\frac{40}{100} \times 1000$

Cancelling two zero, we get,

$=\frac{40}{1}\times 10\\=40\times 10$

Multiplying 4 by 1 we get 4 remaining zero will be added so, 40 multiplied by 10 is equal to 400,

$=400\:gallon$

Therefore the remaining water in the swimming pool is equal to total water in the swimming pool minus water drained out from the pool,

$=1000-400\\=600\:gallons$

Hence 600 gallons of water is left in the swimming pool.
