Question

How to turn degrees to rads? With no calculator!

Answer 1

You seem panicked :D
Not to worry... just multiply the degrees by this:
\[\Large \frac{\pi}{180^o}\] and you'll have your rad ^_^

Cheers...

Answer 2

hahaha :)))

Answer 3

i know, i need to multiply it by pi/180, but that would be easy if i had a calculator and didnt have to do it by hand

Answer 4

Input the angle in the numerator and let it simplify it :)

Answer 5

don,'t forget the pi in the numerator though :)

Answer 6

i know that.

Answer 7

then what is your question then?

Answer 8

my problem is the simplifying it, I cant remember how to long divide correctly Lets say I want to turn 45 to rads, I know it will be 45/180, but I forgot how to long divide that

Answer 9

or you are basically saying, how to make it in lowest terms right?

Answer 10

yes. thats my only problem

Answer 11

i just cant remember correctly how to long divide it

Answer 12

you take what is the highest common factor of the numerator and denominator ,

In the case of 45 / 180 , it will become like this , (45) (1) / (45) (4), then we cancel out common terms :)

Answer 13

what if i have 60/180, would it be the same thing? or 270/180

Answer 14

yep :) get the highest common factor :) (60)(1) / (60)(2) :)

Answer 15

in 270/180 , its (60)(3)/(60)(2)

Answer 16

do you get it now? :)

Answer 17

a little, sorry I havent done mental math in a while. but umm, how are you getting the 3 from (60)(3), i know its the greatest common factor, but can you explain the process a bit more?

Answer 18

270/180 , we get the Highest common factor of 270 and 180. It is 60 right? :) so in the numerator what number would we multiply 60 to get to 270? its 3 right? , in the denominator what number would we multiply 60 to get to 180? its 2 right? :) Do you get it now ? :)

Answer 19

yes, thank you. Sorry, i know its a really stupid question, I just haven't done this in a while. could u go over long division, bc i forgot that too?

Answer 20

\[is \it like , 45\div 180 ?\]

Answer 21

\[45 \div 180\] ?

Answer 22

yes

Answer 23

you read this as 180 divided by 45.
So if you would divide 180 by 45,

Its like, " How many times 45 goes into 180 ? "

Answer 24

are you getting this?

Answer 25

we can also put this in equation, :)

(45) ( x ) = 180

Answer 26

yes, but my question is a little past that. its when you start dividing, I remember something about how I have to find a number close that multiplies close to 180 or something like that, thats were im getting confused

Answer 27

Is this the listing method ?

Answer 28

idk, i learned it when i was 6, im now 18, i cant remember it fully

Answer 29

Is this getting the GCF of 2 numbers? is your question like that?

Answer 30

its like that. I just dont know how to start the process
