Step 1
$2 x = 17.2$
Divide 2 on both sides,
$\frac{2 x}{2} = \frac{17.2}{2}$
$\frac{2 x}{2}$
Based on the definition,
If the divisor is a whole number, we have to place the decimal point in the quotient directly above the decimal point in the dividend and then divide as whole numbers.
$\frac{2 x}{2} = \frac{x}{1}$
$x$
$\frac{2 x}{2} = x$
$\frac{17.2}{2}$
Based on the definition,
If the divisor is a whole number, we have to place the decimal point in the quotient directly above the decimal point in the dividend and then divide as with whole numbers.
$\frac{172}{2}$
$= 86$
The number of decimal places in the dividend is 1.
Place a point one number to the right of the number
8.6
$\frac{17.2}{2} = 8.6$
Substitute $\frac{2 x}{2} = x$ and $\frac{17.2}{2} = 8.6$ in $\frac{2 x}{2} = \frac{17.2}{2}$

$x = 8.6$
