A stone is a unit in the British customary system. Use the conversion 14 pounds = 1 stone to check the equivalencies on a 1973 Australian stamp. Is 100 kilograms approximately 15 stone 10 pounds?

OpenStudy (anonymous):

how many kilograms are in a pound

OpenStudy (bbb911):

2.20

OpenStudy (anonymous):

so 14 lbs=1 stone. 100kg=15 stones?

OpenStudy (bbb911):

do i have to multiply in this one cos i am a little confused

OpenStudy (anonymous):

i dont get the question, " Is 100 kilograms approximately 15 stone 10 pounds", is the question exactly how it was written?

OpenStudy (bbb911):

i think is asking if its approximately that the answer is yes but i dont know how it would be that answer

OpenStudy (anonymous):

well 100 kilograms equals how many pounds?

OpenStudy (bbb911):

so i convert 100 kg to pounds right?

OpenStudy (anonymous):

yeah

OpenStudy (bbb911):

i got 22,000

OpenStudy (anonymous):

to convert from kilograms to pounds 1kg=2.20462 therefore it should be \[100kg*\frac{ 2.20462lb }{ 1kg }=what?\]

OpenStudy (anonymous):

it would be 220 pounds.

OpenStudy (bbb911):

okay now what would i do next?

OpenStudy (anonymous):

now do the same thing i did and convert pounds to stone

OpenStudy (bbb911):

thts what i dont get frm pounds to stone

OpenStudy (anonymous):

so to convert from pounds to stone you know that 14 pounds = 1 stone so put it in the same form i showed above and you get \[220 lb*\frac{ 1 stone }{ 14lb }=what?\]

OpenStudy (anonymous):

what ever you are trying to solve for when you know the conversion factor put it on top

OpenStudy (bbb911):

which is 15.71 since it told me to round to two decimal places

OpenStudy (anonymous):

Yup which is approximately 15 stone and 10 lb depending on decimals on all

OpenStudy (anonymous):

and all*

OpenStudy (bbb911):

ahhh i get it now thank you so muh both of u

OpenStudy (anonymous):

sorry i had to go towards the middle!

OpenStudy (bbb911):

OpenStudy (anonymous):

welcome just remember how to use the conversion factor and whatever you are solving for put it on top!
