Step-by-step explanation:
Using Place Value Chart, we could identify the place value of the given decimal to determine if the given decimal are applicable to the given verbal phrase:
Table #1 for A. 1.1
[tex]\begin{tabular}{|c|c|c|}\cline{1-3}Ones & Decimal point & Tenths\\\cline{1-3}1 & . & 1\\\cline{1-3}\end{tabular}[/tex]
Using this chart, we read it as 'one and one-tenths'.
Table #2 for B. 1.01
[tex]\begin{tabular}{|c|c|c|C|}\cline{1-4}Ones & Decimal point & Tenths & Hundredths\\\cline{1-4}1 & . & 0 & 1\\\cline{1-4}\end{tabular}[/tex]
Using this chart, we read it as 'one and one-hundredths'.
Table #3 for C. 1.001
[tex]\begin{tabular}{|c|c|}\cline{1-2}Ones & 1\\\cline{1-2}Decimal point & .\\\cline{1-2}Tenths & 0\\\cline{1-2}Hundredths & 0\\\cline{1-2}Thousandths & 1\\\cline{1-2}\end{tabular}[/tex]
Using this chart, we read it as 'one and one-thousandths'.
Table #4 for D. 1.1000
[tex]\begin{tabular}{|c|c|}\cline{1-2}Ones & 1\\\cline{1-2}Decimal point & .\\\cline{1-2}Tenths & 1\\\cline{1-2}Hundredths & 0\\\cline{1-2}Thousandths & 0\\\cline{1-2}Ten-thousandtgs & 0\\\cline{1-2}\end{tabular}[/tex]
Using this chart, we read it as 'one and one-tenths' same as the first choice.
Note: Any decimal that had zero-digit after the last non-zero digit are just the same as there is no zero-digit.
Therefore, the answer is letter C. 1.001.
