2.0 is? times greater than 0.02

2.0 is 100 times greater than 0.02. When you have two numbers that are just separated by zeroes, simply count the number of zeroes and multiply the smaller number by a multiple of ten with the same number of zeroes to get the larger number. For instance, if you were to have 40 and 0.0004, you can just count the number of decimal places between them (in this case 4), and put the same number of zeroes behind a 1 (10,000). Then, if you multiply 0.0004 by 10,000, you should get 40. Likewise, if you multiply 0.02 by 100, you should get 2.

2.0 is 100 times greater than 0.02 because 0.02 x 100 = 2
