Answer 1

`18.5105\,\,kg`

Explanation:

Given:

The weight of a
`5` gallon bottle water is
`18.5 \,\, kg`.

The weight of a
`1` gallon bottle water is
`10,500\,\,mg`

To find:

Total weight of the two bottles of water in kg

Solution:

Weight of a
`5` gallon bottle water
`=18.5\,\,kg`

Weight of a
`1` gallon bottle water
`=10,500\,\,mg`

Use
`1\,\,mg=(1)/(1000000)\,\,kg`

So,

Weight of a
`1` gallon bottle water
`=(10,500)/(1000000) \,\,kg`

`=0.0105\,\,kg`

Total weight of the two bottles of water in kg
`=18.5+0.0105=18.5105\,\,kg`
