Question

change in the form of p/q : 0.407(bar on 7)

Answer 1

Here is your answer it may help....

Answer 2

you can go with the trick
write .407 as 407/9 because bar is only on 7 so only one 9
next subtract the no. that doesn't has bar
so
$\frac{407 - 40}{9} = \frac{367}{9}$
now since there are two non repeating numbers ( 4 and 0) so put two zero next to 9
so answer is
$\frac{367}{900}$
this is the answer
