does anyone know fractions?

OpenStudy (anonymous):

tell me ur question

OpenStudy (anonymous):

ok it is equvialant frations

OpenStudy (anonymous):

wat is the numbers

OpenStudy (anonymous):

ok five equvilant fractions for 2 out of 3

OpenStudy (sandra):

ok so 2 out of 3 can be written as 2/3

OpenStudy (sandra):

all you have to do is multiply both the top and bottom by 5 different numbers

OpenStudy (sandra):

since if you multiple both the top and bottom, the actual fraction will be the same (equivalent)

OpenStudy (sandra):

so for example you can multiple 2/3 * 2/2, and you will get 4/6

OpenStudy (sandra):

which is equivalent to 2/3

OpenStudy (anonymous):

ok

OpenStudy (sandra):

so go ahead and do it for 2-6

OpenStudy (sandra):

and you will have five equivalent fractions

OpenStudy (anonymous):

but i dont know how to times fractions

OpenStudy (sandra):

oh ok. well multiplying fractions is easy enough.

OpenStudy (sandra):

all you do is multiply straight across both the top and bottom

OpenStudy (sandra):

so 2/3 * 2/2 = 2*2/3*2 = 4/6

OpenStudy (sandra):

2/3 * 3/3 = (2 x 3)/(3 x 3) = 6/9

OpenStudy (sandra):

2/3 x 4/4 = (2 x 4)/ (3 x 4) = 8/12

OpenStudy (sandra):

now if you wanted to multiply (this is just for example/practice) 2/3 x 3/4, that would again be multiplying the top x top / bottom x bottom, so (2 x 3)/ (3 x 4) = 6/12

OpenStudy (anonymous):

OpenStudy (sandra):

the reason 4/6, 6/9, and 8/12 are equivalent fractions, are because in each case you really just multiplied by 1

OpenStudy (sandra):

well, I gave you the first three equivalent fractions

OpenStudy (sandra):

4/6, 6/9, and 8/12

OpenStudy (sandra):

so what is 2/3 x 5/5?

OpenStudy (sandra):

it's (2 x 5)/ ( 3 x 5)

OpenStudy (sandra):

so 10/15

OpenStudy (sandra):

now if you do 2/3 x 6/6 , you will have the answer

OpenStudy (anonymous):

its basically all of the fractions that when u reduce gives you 2/3 once its completely reduced to its simplest form

OpenStudy (anonymous):

i was tryen to type that but my mouse was stuck

OpenStudy (sandra):

it's k, sometimes you just have to refresh (not sure why)

OpenStudy (sandra):

so I gave you four equivalent fractions

OpenStudy (anonymous):

OpenStudy (sandra):

correct =)

OpenStudy (sandra):

so you now have five equivalent fractions

OpenStudy (anonymous):

yea see its easy

OpenStudy (sandra):

thanks need =), gl star!

OpenStudy (anonymous):

4

OpenStudy (anonymous):

yea no problem

OpenStudy (anonymous):

wat math u got?
