Multiply: $2.473\times 100$

When a decimal number is multiplied by 10, 100 or 1000, the digits in the product are the same as in the decimal number but the decimal point in the product is shifted to the right by as many places as there are zeros over one.

Therefore,

$2.473\times 100=247.3$

Here we multiplied the number 2.473 by 100 so we move the decimal point two places to the right.
