Question

Let a=3/4 and b=1/5. If a*x=b, then what is x?

Answer 1

In general, any equation like
`ax=b` (assuming
`a \\eq 0`) is solved by

`x= (b)/(a)`

So, in your case, the solution is

`x = ((1)/(5))/((3)/(4))`

Dividing by a fraction means to multiply by the inverse of that fraction:

`((1)/(5))/((3)/(4)) = (1)/(5) \cdot (4)/(3) = (4)/(15)`
