Final answer:
The question is about the place value of the middle '5' in the decimal 0.555. The value of the middle '5' is 1/10 the value of the '5' to its left because each place value to the right is ten times smaller in a decimal number.
Step-by-step explanation:
The question asks about place value in the decimal number 0.555. Place value refers to the value of a digit based on its position within a number. To clarify, in the number 0.555, the first '5' is in the tenths place, the second '5' is in the hundredths place, and the third '5' is in the thousandths place. The value of the second '5', which is in the hundredths place, is indeed 1/10 the value of the first '5', because each subsequent place value to the right in a decimal is ten times smaller than the one to its left. Therefore, the middle '5' in the number 0.555 has a value of 5/100, which is ten times smaller than the '5' to its left, which has a value of 5/10.
