To multiply a whole number by 100, add two zeros to the right. For example, 54 x 100 = 5400. To multiply any decimal number by 100, move the decimal point two positions to the right. For example, 4.1178 x 100 = 411.78, and 4.9 x 100 = 490. Note that in the last example I filled out missing digits with zero. Also note that 490 is the same as 490.0, so you can assume that in 490 there is an implicit decimal point to the right of the number.
490 = 490
