Step-by-step explanation:
The simplest form of the given expression
is 
<u>Solution:</u>
Given, expression is 3 11/12 – 1 4/12 
We have to find the simplest form of the value derived from the given expression.
Now, first let us solve the given equation.

converting mixed fractions to improper fractions.


As there are no common terms to cancel it is in lowest form.
Hence, the lowest form of the given expression is
