Answer 2

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

Step-by-step 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$=\text{weight in pound}\times16$

                                 $20\times16$

                                 $320$ $\text{ounce}$

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

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

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