Answer 2

Answer:
`327`
`\text{ounce}`

Explanation:

Given: On the way home from school, ross wears his
`20` pound backpack and carries his
`7` ounce lunchbox.

To Find: how many ounces does he carry in total.

Solution:

Weight of Ross's backpack
`=20`
`\text{pound}`

Weight of Ross's lunchbox
`=7`
`\text{ounce}`

Now,

As unit of weight of backpack and lunchbox is different, we need to convert it.

`1`
`\text{pound}`
`=16`
`\text{ounce}`

Now weight of backpack is
`=\text{weight in pound}*16`

`20*16`

`320`
`\text{ounce}`

Total ounces carried by Ross
`=\text{weight of backpack}+\text{weight of lunchbox}`

`320+7`
`\text{ounce}`

Hence Total ounce carried by Ross is
`320+7`
`\text{ounce}`
