Question

A bathtub is filled with 38 1/3 gallons of water. If 2 3/5 gallons splash out , how much water is left in the tub?

Answer 1

`35 (11)/(15) \: \: gallons \: of \: \: water`

Explanation:

The volume of water in the bathtub is 38⅓ gallons of water.

If

`2 (3)/(5)`

gallons splash out, then the volume left is

`38 (1)/(3) - 2 (3)/(5)`

We convert to improper fraction to get:

`(115)/(3) - (13)/(5)`

We find LCM to get:

`(5 * 115 - 3 * 13)/(15)`

`(575 - 39)/(15) = (536)/(15)`

`= 35 (11)/(15)`
