#3 xx 1 + 1 xx 1/10 + 4 xx 1/100 + 1 xx 1/ 1000#

Explanation:

In expanded notation each digit is written as a product of the digit and the place value that it occupies.

The 3 is in the 1's place a whole number.
The first 1 is in the tenth's place (0.1) or 1/10
the 4 is in the hundredth's place (0.01) or 1/100
The second 1 is in the thousandth's place (0.001) or 1/1000

so # 3 xx 1 + 1 xx 1/10 + 4 xx 1/100 + 1 xx 1/1000#
