If one barrel of crude oil provides 4 million BTUs of energy, how many BTUs of energy will 5 liters of crude oil provide? 1 barrel of oil= 160L

rebeccaxhawaii (rebeccaxhawaii):

cross multiply

OpenStudy (janu16):

But how to set it up?

OpenStudy (anonymous):

4 mil/160= answer then x 5

OpenStudy (misssmartiez):

1/160

OpenStudy (misssmartiez):

actually.

OpenStudy (misssmartiez):

unit rate. 4 over 160 isn't a unit rate?

OpenStudy (misssmartiez):

or are you trying to set it up in a cross multiplication format?

OpenStudy (anonymous):

per liter, there are 25000 BTU

OpenStudy (misssmartiez):

|dw:1457172769716:dw|

OpenStudy (misssmartiez):

wouldn't it be that?

OpenStudy (misssmartiez):

or you are finding, ohh, I see! You weren't finding how many Ls of 4 barrels, I get it, carry on~

OpenStudy (anonymous):

wait are you commenting on me

OpenStudy (misssmartiez):

sooo,,, we are finding out _ liters in 5 barrels right?

OpenStudy (misssmartiez):

or the BTUs. @Le_Asien

OpenStudy (anonymous):

no, how many BTU in 5 LITERS not barrels

OpenStudy (misssmartiez):

Gotcha

OpenStudy (janu16):

So 5 divided by 160 times 4 million?

OpenStudy (misssmartiez):

honestly, I'd do 160 x 4 = 640 million. 640 million / 5 = BTU energy

OpenStudy (anonymous):

IDK

OpenStudy (misssmartiez):

Since it is unit conversion,

OpenStudy (misssmartiez):

Overall, not totally sure.

OpenStudy (janu16):

Ok

OpenStudy (misssmartiez):

1 barrel, 160L, or 4 million BTUs. Cross multiply that, 640 million. Then to find 5Ls, I just divided the product, 128 million BTUs, though it still confuses me.
