$\frac{1}{2} = 0.5$ $1/2=0.5$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Why is that?

The structure of a decimal is:

Decimal point
$↓$ $" "darr$
$units + 10^{ths} + 100^{ths} + 1000^{ths}$ $"units" + 10^("ths") + 100^("ths")+1000^("ths")$ + ..and so on

So lets see if we can convert $\frac{1}{2}$ $1/2$ as one of these.

Multiply by 1 and you do not change the actual value. However, 1 coms in many forms.

$\frac{1}{2} \to [\frac{1}{2} \times 1] = [\frac{1}{2} \times \frac{5}{5}] = \frac{1 \times 5}{2 \times 5} = \frac{5}{10}$ $1/2 ->color(green)( [1/2color(red)(xx1)] " "=" "[1/2color(red)(xx5/5)] " "=" "(1xx5)/(2xx5)" "=" "5/10 )$

..........................................................................
So we have:

$units + 10^{ths} + 100^{ths} + 1000^{ths}$ $"units" + 10^("ths") + 100^("ths")+1000^("ths")$ + ..and so on
$↓ ↓$ $" "darr" "darr$
$. 0 + \frac{5}{10}$ $" "color(white)(.)0 + 5/10$

This is written as $0.5$ $0.5$

So $\frac{1}{2} = 0.5$ $1/2=0.5$
