A rational number is a number that can be written as a fraction.

The square root of 34 is equal to ~5.83. This number cannot be written as a fraction.

Pi is not a rational number. Its digits stretch into infinity and it does not have any factors.

The square root of 64 is a rational number. The square root of 64 is 8, which can be written as a fraction, as well as being an integer.

The square root of 102 is equal to ~10.1. This is not a rational number and cannot be written as a fraction.

Therefore, the square root of 64 (Or 8) is a rational number.

Hope this helps! :)

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

Solution:

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 $\frac{31}{12}$
