Betty used a calculator to find the [product](https://artofproblemsolving.com/wiki/index.php/Product) $0.075 \times 2.56$.  She forgot to enter the decimal points.  The calculator showed $19200$.  If Betty had entered the decimal points correctly, the answer would have been
$\text{(A)}\ .0192 \qquad \text{(B)}\ .192 \qquad \text{(C)}\ 1.92 \qquad \text{(D)}\ 19.2 \qquad \text{(E)}\ 192$
The [decimal point](https://artofproblemsolving.com/wiki/index.php/Decimal_point) of 0.075 is three away from what Betty punched in, and that of 2.56 is two away. The decimal point is therefore $3+2=5$ units to the left of where it should be, so we would want $.19200\Rightarrow \mathrm{(B)}$.
