For more on marking an answer as the "Best Answer", please visit our FAQ.As the operations are written in the first line, I read it to mean: 1 divided by (5 - 3) divided by (6 - 3) and then minus 1.
1 divided by (5 - 3) = 1 divided by 2 = 1/2
1/2 divided by (6 - 3) = 1/2 divided by 3 = 1/6
1/6 - 1 = -5/6
But if the original problem was written to intend (5 - 3) divided by (6 - 3) to be done first (as it could well have been) then we have :
(5 - 3) divided by (6 - 3) = 2 divided by 3 = 2/3
Then 1 divided by 2/3 = 3/2
3/2 - 1 = 1/2
The solution is one or other of these.
if you dont want the answer DO NOT read on.
This was a problem that some one gave me at work, they are supposed to be the same problem but didnt quite work out that way. im not very good at maths so i got the answer as 0.5 as most of you probably did.
the actual answer was -0.83333333, the (5-3)/(6-3) = 2/3 = 0.6666666667 then you do 1/0.66666667 then minus the 1. which equals -0.83333333.
