what is 1 1/5 gallon * 8 1/3 lbs/gallon?

you'll want to convert both numbers to improper fractions before multiplying.

I think it's A

whpalmer4 · Answer

oh, come on, this isn't difficult to do.

8 1/3 = (8*3+1)/3 = 25/3
1 1/5 = (1*5+1)/5 = 6/5

25/3 * 6/5 = (25*6)/(3*5) = 150/15 = ???

10?

anonymous · Answer

omg I added to the wrong thing lol he is right

whpalmer4 · Answer

yes, 10 is correct.

whpalmer4 · Answer

as you have answer choices here that aren't all that close together, you could just estimate it, too.  1* 8 1/3 = 8 and a bit.  add another 1/5 of that, that's about 1.6.  8 and a bit plus almost 2 gives you about 10.  B is obviously wrong, it isn't nearly big enough, and A and D are too big.
