Denominator : The denominator of a fraction $\frac{a}{b}$ is the number $b$ below the fraction bar.
Division : Division is the mathematical operation that divides objects equally into groups. More generally $x\div y$ is defined as the number that if multiplied by $y$ equals $x.$
Follow from : A second equation or inequality follows from an initial equation or inequality if all solutions of the initial equation are also solutions from the second equation or inequality. It does not necessarily have to be the case that all solutions of the second equation or inequality have to by solutions of the first inequality. For example $x^2=1$ follows from $x=1$, but $x^2=1$ is not equivalent to $x=1$ as -1 is a solution of $x^2=1$ but not a solution of $x=1.$
Fraction : A fraction is a number that can be written as $\frac{a}{b}$ with an integer $a$ and a natural numbers $b.$ A fraction $\frac{a}{b}$ is the result of the division $a\div b.$ Examples of fractions are $\frac{1}{2}, -\frac{2}{3}$ and $\frac{3}{2}.$
Multiplication : Multiplication is the mathematical operation that is a shorthand for adding the same amount several times. For example $3\cdot 4=4+4+4=12.$
Numerator : The numerator of a fraction $\frac{a}{b}$ is the number $a$ above the fraction bar.
One eighth : One eighth is the number $\frac{1}{8}=0.125.$
Unit fraction : A unit fraction is a fraction of the form $\frac{1}{n}$ for a natural number $n$. Examples of unit fractions are $\frac{1}{2}$ and $\frac{1}{23}.$
$\frac{4}{8}\div \frac{1}{8}=?$
