Step-by-step solution

To solve this problem, we will decode the place value information presented in the chart and form the number step-by-step.

Here's the breakdown of what each area in the place value chart represents:

  • Hundreds of Thousands: 11
  • Tens of Thousands: 00
  • Thousands: 22
  • Hundreds: 00
  • Tens: 11
  • Units: 55

By combining these place values, we can form the number by considering each digit's value given its position:

The numerical value can be broken down as follows:
- 11 in the hundreds of thousands place represents 100,000100,000.
- 00 in the tens of thousands place represents 00.
- 22 in the thousands place represents 2,0002,000.
- 00 in the hundreds place represents 00.
- 11 in the tens place represents 1010.
- 55 in the units place represents 55.

Summing these values, we have:
100,000+0+2,000+0+10+5=102,015. 100,000 + 0 + 2,000 + 0 + 10 + 5 = 102,015.

Thus, the number represented by the place chart is 102,015 102,015 .

This corresponds to choice .

Key Points to Remember

Essential concepts to master this topic
  • Place Value: Each position represents a different power of ten
  • Technique: Read from left to right: 1 hundred thousand + 0 ten thousands + 2 thousands + 0 hundreds + 1 ten + 5 units
  • Check: Verify by adding place values: 100,000+0+2,000+0+10+5=102,015 100,000 + 0 + 2,000 + 0 + 10 + 5 = 102,015

Common Mistakes

Avoid these frequent errors
  • Reading zeros as empty spaces
    Don't skip over zeros or treat them as nothing = wrong number of digits! Zeros are placeholders that maintain position values. Always include zeros when writing the standard form number.

FAQ

Everything you need to know about this question

Why are there zeros in some places but not others?

+

Zeros are placeholders that show a place value has no value. In this chart, there's no digit in the tens of thousands or hundreds places, so we use 0 to hold those positions.

How do I know which direction to read the chart?

+

Always read from left to right, starting with the largest place value. Think of it like reading a sentence - millions, then hundred thousands, then ten thousands, and so on.

What if I mix up the place value names?

+

Remember the pattern: each place is 10 times bigger than the one to its right. Use the headers in the chart to double-check: Millions, Hundred Thousands, Ten Thousands, Thousands, Hundreds, Tens, Units.

How can I check if my answer makes sense?

+

Look at the first digit and its place value. Here, 1 is in hundred thousands, so your answer should be between 100,000 and 199,999. The answer 102,015 fits this range!

What's the difference between 102,015 and 1,002,015?

+

The number of digits! 102,015 102,015 has 6 digits (hundred thousands), while 1,002,015 1,002,015 has 7 digits (millions). Count the place values in your chart carefully.
