Convert Mixed Numbers to Decimals: Reading a Place Value Chart

To solve the problem, we must correctly interpret the chart and combine the digits into a complete decimal number based on their place values:

• The number in the thousands place is 3, so it represents $3 \times 1000 = 3000$.
• There are no numbers explicitly shown in the hundreds, tens, and ones places, which are assumed as zeros, hence their contribution is zero.
• The digit after the decimal has a five in the hundredths place. Therefore, it represents $5 \times 0.01 = 0.05$.

To obtain the final number, we sum the contributions of each place value:

• The overall contribution from the thousands place is 3000.
• The decimal portion contributed by the hundredths place is 0.05.

Adding these up gives:

$3000 + 0.05 = 3000.05$

Thus, the number represented by the chart in decimal form is $\textbf{3000.05}$.
