Jake because 45.21×10=452.1 which is not a whole number, and 8.22×10=82.2 which is also not a whole number, but 45.21×100=4521 which is a whole number, and 8.22×100=822 which is also a whole number. When you multiply a number with 1 and 0s behind it (ex: 10,100,1000, etc) You just more the decimal place the number of 0s you have (ex: 2.0×100= 200, 3.5×1000=3500)
