Question

What's 3/4x=1/8? because i don't know

Answer 1

Ok so it could be 2 things
(3/4)x=1/8 or
3/(4x)=1/8

if it is (3/4)x=1/8, go to AAAAAAAAAAAAA

if it is 3/(4x)=1/8 go to BBBBBBBBBBBB


AAAAAAAAAAAAA
(3/4)x=1/8
multiply both sides by 4/3 to clear fraction ( since 3/4 times 4/3=12/12=1)
1x=4/24
x=1/6


BBBBBBBBB
3/(4x)=1/8
multiply both sides by 4x
3=(4x)/8
multiply both sides by 8
24=4x
divide bohs ides by 4
6=x




if it is (3/4)x=1/8, then x=1/6
if it is 3/(4x)=1/8, then x=6

Answer 2

To get the answer, you have to isolate x by multiplying by the reciprocal of the coefficient:
$\frac{3}{4}x= \frac{1}{8} \\ \frac{4}{3} ( \frac{3}{4}x)= (\frac{1}{8} )( \frac{4}{3}) \\ \frac{12}{12}x= \frac{4}{24} \\ x = \frac{1}{6}$ 

The answer is x = 1/6.

Hope this helps!
