5. Wrong
how about writing your
3.671 less than 3.67 as
3.671 less than 3.670
can you tell now?
6. ok
7. If I recall my nonmetric units, there are 16 oz in a lb, so ...
$5.39/12 = $.45
$7.39/20 = $.37
$4.89/10 = $.49
$6.39/16 = $.40
So what do you think?
8. wrong
the 8gal + 3gal alone would already add up to 11gal
8 gall,7q + 3 gal,2q = 11 gal,9q
= 13gal,1q
