Question

What is the sum ?

Answer 1

(1+b^2)/2b

Answer 2

O.o its actualy quite easy
are u confused?

Answer 3

Yes

Answer 4

\[1/2b +b/2 = \frac{ 2+ 2b^2 }{ 4b } =\frac{ 2(1+b^2) }{ 4b } =\frac{ 1+b^2 }{ 2b }\]

Answer 5

got it?

Answer 6

nope

Answer 7

umm
okay
let me simplify the 1st step

Answer 8

its okay you dont have to show me

Answer 9

Im gonna be confused anyways

Answer 10

\[\frac{ 1 }{ 2b } +\frac{ b }{ 2 } = \frac{ 1*2 +2b*b }{ 2b*2 }\]

Answer 11

now?

Answer 12

hmm,okay
nvm.
just check the formula
its easy

Answer 13

I kinda get it thank you.

Answer 14

no probs

Answer 15

fractions can only be added if they have the same denominator

Answer 16

lol

Answer 17

in order to add them together, you need to convert one of the fraction, which can be done by multiplying by 1 or 2/2 or 3/3 or b/b, etc

Answer 18

lol

Answer 19

:P

Answer 20

rather than giving steps, you should really try to explain it

Answer 21

i GET IT THOUGH

Answer 22

It'll always confuse me but i get it

Answer 23

your next question is avariation of cross multiplying

Answer 24

well
its not like i dont want to
and ur statement "fractions can only be added if they have the same denominator" is wrong anyway

Answer 25

the formula u are looking for is
\[\frac{ a }{ b }+ \frac{ c }{ d } = \frac{ a*d+b*c }{ b*d }\]

Answer 26

and for the common denominator u said
thats
\[\frac{ a }{ b }+\frac{ c }{ b } =\frac{ a+c }{ b }\]

Answer 27

there is no such a thing as fractions cant be added xD
