Question

Jenna has 6 scarfs that are each 2 feet long and another 6 that are each 9 inches long. What length of material does she have in total?

Answer 1

First multiply each unit individually: `6xx2=12` feet and `6xx9=54` inches.
Now we can divide the number of inches by `12` to convert to feet (as much as possible): `54/12= 4` remainder `6`.
Add the `4` ft to the `12` ft and we have `16` ft `6` inches of material.

Explanation:

(I would say 'scarves' as the plural, but that might just be a local difference.)
