First, we can write:

x

=

3

.

¯¯¯¯

24

Next, we can multiply each side by

100

giving:

100

x

=

324

.

¯¯¯¯

24

Then we can subtract each side of the first equation from each side of the second equation giving:

100

x

x

=

324

.

24

We can now solve for

x

as follows:

100

x

1

x

=

(

324

+

0

.

¯¯¯¯

)

(

3

+

)

x

=

324

+

Now, we can convert this improper fraction to a mixed number:

x

=

107
