Question

A fish tank holds 14 liters of water. If we use a scoop that holds one-third of a liter, how many scoops will we need in order to fill the entire fish tank?

Answer 1

We will need 42 scoops in order to fill the entire fish tank.

Explanation:

Given:

A fish tank holds 14 liters of water.

We use a scoop that holds one-third of a liter.

Now, to find the scoops in order to fill the entire fish tank.

One scoop holds :

`(1)/(3)\ of\ 1\ liter.`

=
`(1)/(3) * 1`

=
`(1)/(3) \ liter.`

Total liters of water fish tank holds = 14 liters.

Now, to get the number of scoops we need to fill the entire fish tank we divide total liters of water fish tank holds by quantity of water one scoop holds:

`14/ (1)/(3)`

As, we change the division into multiplication one side of the number reciprocals:

=
`14* 3`

`=42\ .`

Therefore, we will need 42 scoops in order to fill the entire fish tank.
