Felix writes the number 15.205. Then he writes another number in which the digit 2 has 1/10 the value as it has in the first number. Which could be the second number he writes?

15.025

16.025

To find the second number Felix writes where the digit 2 has 1/10 the value as it has in the first number (15.205), we need to understand the place value system.

In the first number, 15.205, the digit 2 is in the hundredth place. The digit 2 in this number has a value of 2 * 0.01 = 0.02.

Now, if Felix wants to write a number where the digit 2 has 1/10 the value, we need to divide 0.02 by 10. This gives us 0.002.

Therefore, the second number Felix writes could be 15.2005, where the digit 2 has 1/10 the value it had in the first number.
