Here, you will practice finding reciprocals (multiplicative inverses) of whole numbers and fractions.
For $\,x\ne 0\,$, the reciprocal of [beautiful math coming... please be patient] $\,x\,$ is $\displaystyle\,\frac{1}{x}\,$.
In particular, the reciprocal of [beautiful math coming... please be patient] $\displaystyle\,\,\frac{a}{b}\,\,$ is [beautiful math coming... please be patient] $\displaystyle\,\,\frac{b}{a}\,\,$.
The number
[beautiful math coming... please be patient]
$\,0\,$ does not have a reciprocal, since
division by zero is not allowed.
For all other numbers,
a number multiplied by its reciprocal equals
[beautiful math coming... please be patient]
$\,1\,$: $x\cdot \frac1x = 1$
Type in nd (uppercase or lowercase) if the reciprocal is not defined.
Type fractions using a diagonal slash: for example, 1/3 .
