Answer 2

Answer:

Step-by-step explanation:

The decimal expansion of a number is its representation in base-10 (i.e., in the decimal system). In this system, each "decimal place" consists of a digit 0-9 arranged such that each digit is multiplied by a power of 10, decreasing from left to right, and with a decimal place indicating the 10^0=1s place. For example, the number with decimal expansion 1234.56 is defined as

1234.56 = 1×10^3+2×10^2+3×10^1+4×10^0+5×10^(-1)+6×10^(-2)  

= 1×1000+2×100+3×10+4+5×1/(10)+6×1/(100).
