example: 6 times 1/3 = 2
anonymous
  • anonymous
okay
anonymous
  • anonymous
so how would i solve it
jim_thompson5910
  • jim_thompson5910
what term comes after 2/9 ?
anonymous
  • anonymous
im thinking 2/27
jim_thompson5910
  • jim_thompson5910
yep
jim_thompson5910
  • jim_thompson5910
and after that?
anonymous
  • anonymous
2/71
jim_thompson5910
  • jim_thompson5910
81, not 71
jim_thompson5910
  • jim_thompson5910
so we have these 6 terms 6, 2, 2/3, 2/9, 2/27, 2/81
anonymous
  • anonymous
okay oh i did the math wrong
jim_thompson5910
  • jim_thompson5910
now add up the 6 terms
anonymous
  • anonymous
and it says round you answer to the nearest tens hundreths
anonymous
  • anonymous
i got 64/ 19683
anonymous
  • anonymous
is that right
jim_thompson5910
  • jim_thompson5910
you should get 728/81 when you add up the 6 terms
jim_thompson5910
  • jim_thompson5910
728/81 = 8.98765432098766 approximately
anonymous
  • anonymous
im confused
jim_thompson5910
  • jim_thompson5910
now just round 8.98765432098766 to the nearest ten-thousandths
jim_thompson5910
  • jim_thompson5910
where at?
anonymous
  • anonymous
how would you round it from where
jim_thompson5910
  • jim_thompson5910
8.98765432098766 would round to 8.9877 if you round it to the nearest ten-thousandths
jim_thompson5910
  • jim_thompson5910
find the ten-thousandth's place, then look to the next digit over to see if you round up or not
anonymous
  • anonymous
oh if its greater than 5
jim_thompson5910
  • jim_thompson5910
yes
