Question

Help?! Simplifying complex fraction! I just cant get it.

Answer 1

[y-((3y-7)/7)]/(8/35)+(2/5y)

Answer 2

Every attempt I make is wrong :(

Answer 3

ok i got 5y/4

Answer 4

now i'm going to tell you how i got it

Answer 5

The answer is 5y/2

Answer 6

waaaaaaait

Answer 7

i forgot the 2/5y

Answer 8

imma noob

Answer 9

well i messed up somewhere in adding, but what you're supposed to do is solve each fraction half individually.
so you have
y- 3y-7/7
---------
8/35 + 2/5y
remember how to add rational expressions? Find a common denominator. Start at 8/35 + 2/5y, to make them alike, you could multiply 2/5y by 7 to get 14/35y. For 8/35, you could mulitply by y to get 8y/35y. So now that they're alike, you can just add across
14+8y/35y is now in the denominator.
Now, lets look at the numerator
It's the same thing, remember how to subtract rational expressions?
we can multiply y by 7 to get a common denomiator. Also, remember to turn the minus sign into a plus sign and make everything in the numerator the oppostite of what they are.
y/7 + -3y+7/7
now just add accross.
you get
-2y+7/7
you can cancel out the 7's
now you're just left with -2y

ok, so back to your original problem where you now have
-2y
---------
14+8y/35
this is just saying to divide. Remember how to divide raitonal expressions?
-2y divided by 14+8y/35
you will multiply by the recipocal,remember?
-2y multiplied by 35/14+8y
remember -2y is just -2y/1 in fraction form. Now multiply this rational expression...... WAIT I DID THIS WRONG DIDIN'T I??????????

Answer 10

i got 5/4y damn it

Answer 11

pellet

Answer 12

i got -5/8y now that i redid it

Answer 13

ok i suck i should'nt confuse you anymore

Answer 14

don't give up on me i will do it again with 100 percent focus

Answer 15

ok, it wasn't supposed to be -2y, it was supposed to be 4y

Answer 16

but i messed up again i got 35y/2y+14 pellet@!

Answer 17

sorry i keep on messing up too

Answer 18

let me just get on outta here because i tried it once again but i messed up, again lol sorry i couldn't be much help

Answer 19

the answer is 5y/2

Answer 20

how did you get that?

Answer 21

because now i want to know too

Answer 22

[y-((3y-7)/7)]/(8/35)+(2/5y)
=((7y-3y+7)/7)/((8y+14)/35y)
=((4y+7)/7)*(35y/(8y+14))
=(5y*(4y+7))/(2*(4y+7))
=5y/2

Answer 23

whoa what did you do in =(5y*(4y+7))/(2*(4y+7))

Answer 24

get back in here tuki

Answer 25

when you're cross simplifying,
4y+7 35y
----- * -----
7 8y+14
don't you simplify 4y and 8y by 4y and get 2?
then simplify 7 and 14 by 7 and get 2.
1 35y
---- * -----
7 2+2
then cross simplify 35y and 7 by 7 and get 5y
5y
---
4
???
why is it 5y/2
