Question 1049233
A carpenter goes through 2 3/5 boxes of nails finishing 3 1/2 rooves. How much would he use finishing 8 rooves
==========
I'm not sure that rooves is a word.  Might be roofs.
---
To find roofs per box, divide the # of roofs by the # of boxes.
---
roofs/box = 3.5/2/6 = 35/26
The inverse is boxes/roof = 26/35
----
For 8 roofs:
--> 8*(26/35) = 208/35
