Identify value of $3$ : Identify the value of the $3$ in $20.342$ . The $3$ is in the hundredths place, so its value is $0.03$ .
Calculate $100$ times greater: Calculate the value that is $100$ times greater than $0.03$ . Multiply $0.03$ by $100$ . $\newline$ $0.03 \times 100 = 3$ .
Find number with value $3$ : Look for the number where the digit $3$ has the value of $3$ . The options are: $\newline$ - $108.173$ ( $3$ is in the units place, value = $3$ ) $\newline$ - $423.06$ ( $3$ is in the tens place, value = $30$ ) $\newline$ - $36.25$ ( $3$ is in the tens place, value = $30$ ) $\newline$ - $307.18$ ( $3$ is in the hundreds place, value = $3$ $1$ ) $\newline$ The correct number is $108.173$ , where the $3$ has a value of $3$ .
