Answer:

Step-by-step explanation:

Starting from the rightmost digit, 2, which is the hundredths place, the next digit to the left, which is also 2, is the tenths place. This result, 0.2, is ten times greater than 0.02.

The same pattern applies to the remaining digits. The ones place is 2, and this is ten times the 2 in the tenths place. The tens place is 2, which is ten times the two in the ones place.

Finally, the initial 2 represents ten times the 2 in the tens place.
