Place Value Chart: Converting 11.504 Using Decimal Positions

To solve this problem, we need to write the number shown by the digits in the chart corresponding to their specific place values:

• The digits under 'Whole Numbers' are $1$ in the 'Tens' place and $1$ in the 'Ones' place.
• The digits under 'Fractions' are $5$ in the 'Tenths' place, $0$ in the 'Hundredths' place (implicitly 0 as space is empty in chart), and $4$ in the 'Thousandths' place.

Let's combine these:

The whole number part is $11$ (formed by $1 \times 10 + 1 \times 1$).

The decimal fraction part is $0.504$ (formed by $5 \times 0.1 + 0 \times 0.01 + 4 \times 0.001$).

Thus, concatenating the whole number part and the decimal fraction part yields:

11.504
