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 non-metric 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
