the divided linese are under the numbers... they are not actual division signs.

1/x + 3
1/x + 3/1
1/x + 3x/x
(1+3x)/x
jimthompson5910 (jim_thompson5910):
so
(1/x)+3
is the same as
(1+3x)/x
OpenStudy (anonymous):
okayy.

making
(4)/(x+3)/[(1/x)+3)]
the same as
(4)/(x+3)/[(1+3x)/x]
jimthompson5910 (jim_thompson5910):
to divide the two fractions, you flip the second fraction and you multiply to get this
[ (4)/(x+3) ] * [ x/(1+3x) ]
jimthompson5910 (jim_thompson5910):
do you see what to do from here?
OpenStudy (anonymous):
yeahh.. but the division sign under the four.. isnt actually diving the 4.. its a big line like this l but flipped the other way.. and is bigger than a division symbol.
jimthompson5910 (jim_thompson5910):
can you draw out what you're describing?

yes. |dw:1359785516392:dw|
jimthompson5910 (jim_thompson5910):
ok so basically you have the fraction 4/(x+3) and that's over the expression (1/x) + 3 right?
OpenStudy (anonymous):
so it looks like.. i drew it just like it is asked to me.
jimthompson5910 (jim_thompson5910):
so that would mean that this
