Answer:

343/27

Step-by-step explanation:

Given:- The given fraction is $2\frac{1}{3}$.

To Find:- Cube of the given fraction.

Solution:-

Cube of a number is the result when a number is multiplied to itself three time.

                    Cube = (number)³

The given fraction $2\frac{1}{3}$ is a mixed fraction.

A mixed fraction is a type of fraction formed with combination of a whole number and a fractional part. The whole number is the quotient and the numerator of the fractional part is the remainder.

Here quotient = 2 and remainder = 1 with divisor = 3.

First we need to convert into a proper fraction.

Numerator of the fraction will be = (3 × 2 + 1) ÷ 3

                                                       = 7

Now the fraction is $\frac{7}{3}$.

The cube of the fraction $\frac{7}{3}$ is

=  $\frac{7}{3}$ × $\frac{7}{3}$ × $\frac{7}{3}$

= $\frac{343}{27}$

Therefore cube of $2\frac{1}{3}$ is $\frac{343}{27}$.
