Question

@rational

Answer 1

\[\frac{ 1 }{ a }+\frac{ 1 }{ 2 }=\frac{ 2 }{ a }\]

Answer 2

Solve

Answer 3

@BSwan @hartnn @UnkleRhaukus

Answer 4

multiply both sides of the equation by \(a\),

Answer 5

ok can you write that out please:)

Answer 6

1/a+1/2=2/a
1/2a+a/2a=2/a

1+a/2a=2/a

1+a/2a =4/2a

1+a=4
solve for a

Answer 7

\[\begin{align}\frac{ 1 }{ a }+\frac{ 1 }{ 2 }&=\frac{ 2 }{ a }\\a\times\left(\frac{ 1 }{ a }+\frac{ 1 }{ 2 }\right)&=a\times \frac{ 2 }{ a }\\\frac aa+\frac a2&=\frac{2a}a\\&=\end{align}\]

Answer 8

is that the work im supposed to do to get the answer?

Answer 9

you need to finish it off

Answer 10

ok let me copy down the work first ok

Answer 11

\[
\begin{align}\frac{ 1 }{ a }+\frac{ 1 }{ 2 }&=\frac{ 2 }{ a }\\a\times\left(\frac{ 1 }{ a }+\frac{ 1 }{ 2 }\right)&=a\times \frac{ 2 }{ a }\\\frac aa+\frac a2&=\frac{2a}a\\~\\?&= ?\end{align}
\]

Answer 12

did u really get whats going on in the second step ?

Answer 13

why not simply do fraction sum bhahaha

Answer 14

im copying the work first ok

Answer 15

i would have simply guessed a=2 as two halves make a 1 >.<

Answer 16

@BSwan i dont understand your first step

Answer 17

CAN I COPY THE WORK DOWN HE WORK FIRST!!!!

Answer 18

work first

Answer 19

ok I copied the work down

Answer 20

\(\begin{align}\frac{ 1 }{ a }+\frac{ 1 }{ 2 }&=\frac{ 2 }{ a }\\ \frac{2\times 1 }{ 2 \times a }+\frac{ a\times 1 }{ a\times 2 } &= \frac{ 2 }{ a }\\\frac 2{ 2a }+\frac a{ 2a }&=\frac2{a}=\frac4{2a} \\=\frac{2+a}{2a}=\frac4{2a} \end{align}\)

thus
2+a=4
lol i made a typo first :P
its not 1+a

Answer 21

is that the work I was supposed to copy

Answer 22

lol its ur HW :P
you need to understand not to copy
ask what you dnt understand instead of asking what you should copy

Answer 23

^^
