I'm guessing the answer is 6in.
because the original width of the photo is 8in-4in
which is 4in.
and 8 to 10 is a difference of 2
so add 2 to 4
its 6
4/21 = 12/63 and 2/9 = 14/63
12/63 < 14/63
12. $2
13. $3.33
14. $12/hr
15. 2.75 cups
16. Every hr the sloth walks 1 1/5 mile(mixed number) or 6/5
1.2 miles per hour (because 6/5 mph is equal to 1 and 1 fifth of a mile or .2)
For the $210 one: $30/g
For the $264 one: $33/g
Therefore, the $210 one is a better deal.
