Answer:

#0.12#

Explanation:

Every number divided by #1# remains unchanged!

You may justify this using the fact that #1# is the neutral element for multiplication, id est

#a \cdot 1 = a# for every number #a#

For example, #5 \cdot 1 = 5#

Now, in general, we know how to invert multiplication and turn them into divisions:

#5 \cdot 3 = 15 \implies 15 \div 3 = 5#

So, with one, it works like this:

#a \cdot 1 = a \implies a \div 1 = a#
