The simplest form of the given expression 3\frac{11}{12} - 1\frac{4}{12} is \frac{31}{12}

<u>Solution:</u>

Given, expression is 3 11/12 – 1 4/12 \rightarrow 3 \frac{11}{12}-1 \frac{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.

3 \frac{11}{12}-1 \frac{4}{12}

converting mixed fractions to improper fractions.

=\frac{3 \times 12+11}{12}-\frac{1 \times 12+4}{12}

\frac{36+11}{12}-\frac{12+4}{12}=\frac{47}{12}-\frac{16}{12}=\frac{47-16}{12}=\frac{31}{12}

As there are no common terms to cancel it is in lowest form.

Hence, the lowest form of the given expression is \frac{31}{12}
