Question

omg i seriously need help please help!!!

Answer 1

\[\frac{ 4 }{ w }+\frac{ 4 }{ x }=\frac{ 4 }{ y }\] and wx=y, then the average arithmetic mean of w and x is?

Answer 2

so...\[\frac{ 4x+4w }{ wx }=\frac{ 4 }{ y }\]

Answer 3

?

Answer 4

whytha pelican testies did everyone leave without helping!? fml

Answer 5

\[\frac{ 4 }{ w }+\frac{ 4 }{ x }=\frac{ 4 }{ y }\]
divide by 4
then proceed taking L.C.M

Answer 6

divide what by 4?

Answer 7

yes

Answer 8

...

Answer 9

\[\frac{ 1 }{ w }+\frac{ 1 }{ ? }=\frac{ 1 }{ ? }\]

Answer 10

why do you divide instead of multiplying?

Answer 11

to simplify

Answer 12

oh okay so do i still find the common denominator?

Answer 13

\[\frac{ 1 }{ w }+\frac{ 1 }{ x }=\frac{ 1 }{ y }\]

Answer 14

take L.C.M of L.H.S.

Answer 15

hmmm... can you do this step by step so i understand? i mean i have the answer but i need to know how to do it step by step

Answer 16

\[\frac{ x+w }{ wx }=\frac{ 1 }{ y }\]
but wx=y
\[\frac{ x+w }{ y }=\frac{ 1 }{ y }\]
multiply by y
x+w=1
average of x and w\[=\frac{ x+w }{ 2 }=?\]

Answer 17

wait... i kinda got lost after the second step.... ye are there 2 y in the denominators?

Answer 18

in the second step i have substituted wx=y

Answer 19

ohhhhhhhhhhhhhhhhh i got it omfg wow

Answer 20

1/2

Answer 21

correct.

Answer 22

hey what if the numerator was all numbers divisible by 4 like 4/w + 16/x = 24/y

Answer 23

then you can divide each by 4
1/w+4/x=6/y

Answer 24

oh okay does this apply for all fraction problems no matter what? even if there is a denominator that has actual numbers instead of letters?

Answer 25

if there is common in the denominator then multiply
if common in the numerator divide by common
if to remove the denominator then multiply by L.C.M

Answer 26

okay gotcha thanks so much!!!!!!

Answer 27

what do you mean by gotcha?
it is language of which country?

Answer 28

america it means ok "i got you" it means i understand lol
