OpenStudy (anonymous):

the answers 4 lb 9 oz 3 lb 4 oz 3 lb 9 oz

OpenStudy (anonymous):

same at the other problems you have been working on. figure out how many ounces are in a pound.

OpenStudy (johnweldon1993):

right...but heres a hint....1 pound = 16 ounces sonvert both your weights to only ounces

OpenStudy (johnweldon1993):

convert* sorry about that

OpenStudy (anonymous):

ok, so i subtract them

OpenStudy (anonymous):

yupp!

OpenStudy (johnweldon1993):

once you convert them to ounces...yes you subtract them

OpenStudy (anonymous):

how do i do that

OpenStudy (johnweldon1993):

1 pound = 16 ounces as I have stated above so if you have 9 pounds...how many ounces is that?

OpenStudy (anonymous):

144

OpenStudy (johnweldon1993):

right....then you just add those remaining 5 ounces from before...so 144 + 5 is?

OpenStudy (anonymous):

149

OpenStudy (anonymous):

so do the same for the other, multiply 16 by 5 and then add the 12.

OpenStudy (johnweldon1993):

right...now convert the 5lbs 12 ounces to ounces

OpenStudy (anonymous):

huh

OpenStudy (johnweldon1993):

5 lbs = how many ounces? ***1 lb = 16 ounces***

OpenStudy (anonymous):

is it 80

OpenStudy (johnweldon1993):

and then add the remaining 12 ounces from before *remember it was 5lbs 12 ounces...so add those original 12 to your 80

OpenStudy (anonymous):

so i do 80 plus 12

OpenStudy (johnweldon1993):

correct

OpenStudy (anonymous):

its 92

OpenStudy (johnweldon1993):

correct so now you have 149 ounces....and 92 ounces......and you want the differnce so 149 - 92 is?

OpenStudy (anonymous):

57

OpenStudy (johnweldon1993):

right now that is in ouncs....and you want an answer that includes pounds so divide 57 by 16 to convert your ounces back to pounds

OpenStudy (anonymous):

3.5625

OpenStudy (anonymous):

but these r my answers 4 lb 9 oz 3 lb 4 oz 3 lb 9 oz

OpenStudy (johnweldon1993):

mainly looking for the whole number here......so 3 there are 3 pounds in that many ouces.... so 3 times 16 is....48 you had 57......so 57 - 48....is 9 that's how many ounces you have left over so 3 pounds 9 ounces
