Question

Quinn has 6 bottles of water that each weigh 3/5 pound. What is the total weight of the water bottles? Use the number line to help

Answer 1

The weight of 6 bottles =
`3(3)/(5)\ pounds` or
`3.6\ pounds`

Explanation:

Given:

Total number of bottles = 6

Weight of each bottle =
`(3)/(5)` pound

To find the total weight of 6 bottles.

Solution:

We can plot the number line for six bottles.

We can the plot the weights in another number line.

Each unit represents
`(3)/(5)` pound of weight.

As the number of bottles increase the number of pounds of weight increase by
`(3)/(5)` .

Thus, weight of 6 bottles =
`(3)/(5)+(3)/(5)+(3)/(5)+(3)/(5)+(3)/(5)+(3)/(5)`
`=(18)/(5)` pounds

Converting fraction to mixed number.

`(18)/(5)=3(3)/(5)` pounds

Or in decimals
`(18)/(5)=3.6\ pounds`

Thus weight of 6 bottles =
`3(3)/(5)\ pounds` or
`3.6\ pounds`
