Question

Choose the correct exercise that produces the number 22,005.

Step-by-Step Solution

To solve this problem, we will decompose the number 22,005 using its place values and compare it with the provided answer choices.

First, let's break down the number 22,005:

  • The digit '2' in the ten-thousands place represents 2×10,000 2 \times 10,000 .
  • The digit '2' in the thousands place represents 2×1,000 2 \times 1,000 .
  • The digit '0' in the hundreds place represents 0×100 0 \times 100 .
  • The digit '0' in the tens place represents 0×10 0 \times 10 .
  • The digit '5' in the units place represents 5×1 5 \times 1 .

Combining these values, we have:

22,005=2×10,000+2×1,000+0×100+0×10+5×1 22,005 = 2 \times 10,000 + 2 \times 1,000 + 0 \times 100 + 0 \times 10 + 5 \times 1

Upon reviewing the provided choices, option 3 matches this decomposition exactly:

Choice 3: 22,005=2×10,000+2×1,000+0×100+0×10+5×1 22,005 = 2 \times 10,000 + 2 \times 1,000 + 0 \times 100 + 0 \times 10 + 5 \times 1

Therefore, the exercise that produces the number 22,005 is illustrated correctly in choice 3.

Answer

22,005=2×10,000+2×1,000+0×100+0×10+5×1 22,005=2\times10,000+2\times1,000+0\times100+0\times10+5\times1
