Simplify !??? (1 Viewer)

[trungduong12]

I know my question would sound stupid but yeah... Idk how to do

(1 - 1/19683) over (2/3)

How do u simplify this fraction?? The quickest way possible??

I put in calculator and get 1.499924
It could not show in fraction form
But the answer in the book is in fraction form
I can simplify it but have to break down into steps and takes ages

This is an answer for a series question and therefore should not take too long just to simplify the answer


Anyone help please

So first you have :
1 - 1/19683 = -1/19683 + 1 = (19682/19683)/ 2/3
= 19682/19682 x 3/2
=59046/39366 (further simplify this to get fractional answer)

And yes, 59046/39366 = 1.499924

I hope this helps

and don't worry, you're not stupid it's ok to ask questions! I'm sure other mathematicians here would be more than happy to help!

First thing to notice is:

I know
Thats part of my answer too
But the thing is idk how to simplify from that to 9841/6561

My question is what is the quickest way to simplify that because of course i know how to do in smaller steps -.-

Thats what i did
Of course !!!

My question is: is there any other way (quicker way) to simplify that whole thing?
Because if u get 59046/39366
U then have to keep dividing this number
Which takes time


But still
I dont get how the textbook just doesnt leave it in decimal form like other questions =______=

If you enter it into your scientific calc. doesnt it give the answer in simplest form ? And the reason why they want it in fraction form is because in an exam markers want to give out marks for a proper method

 

[trungduong12]

Do i have to simplify it like that (takes too long) in the hsc ? If that type of question/answer comes up???
But the question doesnt say exact or not exact o___O

I don't have mine right now but if yours is a Casio it should give you the simplified answer ....
