wait we need to divide backwards 11 / 3
UsukiDoll
  • UsukiDoll
ok that sounds better so instead of writing 3 divided by 11 we have to write 11 divided by 3 |dw:1438086137639:dw|

  • anonymous
yes..
UsukiDoll
  • UsukiDoll
so 11 can't divide into 3... therefore we put a 0 on the top... then the decimal point and followed by another 0 inside the radicand (which is the number under the radical symbol )

so 11 can divide into 30 at least twice so 11 x 2 = 22 |dw:1438086248108:dw|

  • UsukiDoll
since 11 can't divide 8 I have to draw another 0 making the number 80 how many times can 11 go into 80? the closest is 7 because 11 x 7 = 77

check this.... further @UsukiDoll can explain, Usaki is awesome.
UsukiDoll
  • UsukiDoll
|dw:1438086315178:dw| then we continue this process until we hit a repeating decimal situation or can get a 0 in the remainder

yeah im following @arindameducationusc
arindameducationusc
  • arindameducationusc
In this division it will repeat 0.272727272727......
UsukiDoll
  • UsukiDoll
an example of a repeating decimal is 0.3555555555555555555555
UsukiDoll
  • UsukiDoll
or what @arindameducationusc wrote.. that was funny Usaki XD
UsukiDoll
  • UsukiDoll
but yes when I'm dividing this for a while I am noticing a pattern.. since I have the remainder 3 .. I have to write a 0 in the radicand and drop it down... again how many times that 11 go into 30? 2 times .. 11 x 2 = 22 then I will get an 8. 11 can't divide into 8 so I have to draw another 0 now I have 80 again then 11 can divide into 80 at least 7 times because 11 x 7 = 77 and then 80-77 = 3 so it's a never ending repeating decimal cycle

  • UsukiDoll
a line is drawn on top of the numbers to indicate that these particular numbers are going to repeat and go on and on and on and on....
UsukiDoll
  • UsukiDoll
@arindameducationusc your work is correct.. :) so fast too XD

btw where did the 77 go @UsukiDoll
UsukiDoll
  • UsukiDoll
oh it was squished in here.
anonymous
  • anonymous
dont we do 77 - 22
UsukiDoll
  • UsukiDoll
|dw:1438086885416:dw| no we don't do 77-22 at all
anonymous
  • anonymous
ahh dont matter thanks for the clarification

  • UsukiDoll
maybe image by image will work |dw:1438087026830:dw|

yeah thanks mate i understand it
UsukiDoll
  • UsukiDoll
noticed that we have a 3 again? we know that 11 can't divide into 3, so we need to write another 0. |dw:1438087323664:dw| now 11 can divide 30 at least 2 times because 11 x 2 = 22 so now we subtract 30-22= 8 wait a sec we have the same pattern over and over again. STOP! We have a repeating decimal. so the final answer is 0.272727272727
