Question

Multiply $345.19\times 100$

Answer 1

Count the number of zeroes in the multiple of $10$. Shift the decimal point to the right equal to the total number of digits in the decimal, i.e. one place if its $10$, two places if its $100$ and so on.

Here, the number of zeroes is two, so, shifting the decimal point to the right side by two place.

Hence, $345.19\times 100=34519$
