so what kinda problems? :d chapter 11 or something?
pooja195
  • pooja195
All of chapter 11 i have 6 quizzes 1 on each section T_T
pooja195
  • pooja195
Do anything it takes i need to pass!!!1

  • zepdrix
\[\Large\rm \frac{3}{5}\div\frac{9}{25}\]Let's start with something like this :d simplify.
pooja195
  • pooja195
5/3

\[\Large\rm \color{red}{\frac{3}{5}}\color{royalblue}{\div}\color{green}{\frac{9}{25}}\]\[\Large\rm \color{red}{Keep}\color{royalblue}{Change}\color{green}{Flip}\]Mmm ok good you got it :)
zepdrix
  • zepdrix
\[\Large\rm \frac{4x^2}{49}\div\frac{x}{7}\]How bout this one?
zepdrix
  • zepdrix
brb
pooja195
  • pooja195
I DONT KNOW T_T
pooja195
  • pooja195
ZEPPY T_T I HATE THIS STUFF D:
zepdrix
  • zepdrix
\[\Large\rm \color{red}{Keep}\color{royalblue}{Change}\color{green}{Flip}\]
zepdrix
  • zepdrix
\[\Large\rm \color{red}{\frac{4x^2}{49}}\color{royalblue}{\div}\color{green}{\frac{x}{7}}=\frac{4x^2}{49}\times\frac{7}{x}\]Are you ok with that first step?
pooja195
  • pooja195
Yes
pooja195
  • pooja195
T_T i cant do this! >:I
zepdrix
  • zepdrix
cross cancel stuff that matches :)
pooja195
  • pooja195
It makes no sense T_T
pooja195
  • pooja195
ZEPPY T_T
pooja195
  • pooja195
Can we skip this one its too hard R_R
pooja195
  • pooja195
i dont like it T_T
zepdrix
  • zepdrix
\[\Large\rm =\frac{4x^{\cancel{2}}}{\cancel{49}7}\times\frac{\cancel{7}}{\cancel{x}}\]Cancel some stuff.
zepdrix
  • zepdrix
I cancelled an x from top and bottom, a 7 from top and bottom.
zepdrix
  • zepdrix
\[\Large\rm =\frac{4x}{7}\]And then just see what's left over.
zepdrix
  • zepdrix
skip it? :d but isn't this what your quiz is on? this kind of stuff?
pooja195
  • pooja195
yes T_T
pooja195
  • pooja195
i dont get it >_< he teached it a diffrent way .-. T_T
zepdrix
  • zepdrix
You really need to get comfortable with this "cancelling" idea. Here is a simple example:|dw:1432860109946:dw|

OOOOOOOOO I GET IT!!! GIVE ME ANOTHER ONE

  • zepdrix
\[\Large\rm \frac{8x^3}{7}\div\frac{2x}{21}\]
pooja195
  • pooja195
nvm i cant do it T_T
zepdrix
  • zepdrix
You understand the first step?\[\Large\rm =\frac{8x^3}{7}\times\frac{21}{2x}\]
pooja195
  • pooja195
Right we flip so we can multiply
zepdrix
  • zepdrix
|dw:1432860681486:dw|
zepdrix
  • zepdrix
Hmm I guess we have to break some stuff down and look for anything that cancels.
pooja195
  • pooja195
nothing cancels
zepdrix
  • zepdrix
Nothing? 0_o
zepdrix
  • zepdrix
Right away you should notice that you have x's in the top, and an x in the bottom. So you know that you'll have AT LEAST one cancellation.
zepdrix
  • zepdrix
|dw:1432860789982:dw|So we can cancel an x out of top and bottom, ya?
pooja195
  • pooja195
wait so after that you factor right?
zepdrix
  • zepdrix
we see a 7 and a 2 in the bottom. So we have to ask ourselves, do the 8 and 21 have any 2 or 7 factors in them? yes try to factor the 8 and 21. this isn't like the factoring we were doing back in last chapters though.
zepdrix
  • zepdrix
factors of 8? factors of 21? :o
pooja195
  • pooja195
168? O-o
zepdrix
  • zepdrix
no. this is not like the other chapter. we're `breaking down` the 8 and 21, not multiplying them together.
zepdrix
  • zepdrix
8 = ?
pooja195
  • pooja195
8=2x2x2 21=7x3
pooja195
  • pooja195
****8=2x2x2x2
zepdrix
  • zepdrix
No, you were right the first time :) lol
zepdrix

|dw:1432861257936:dw|Mmm k good
zepdrix
  • zepdrix
so cancel some stuff.|dw:1432861329403:dw|ya?
