Explanation:
We need to find the
place value of a specific digit in each number. Remember:
- Place value means: *what is the value of that digit based on its position?*
For example, in 6725, the digit
7 is in the
hundreds place, so its place value is
700 (not just 7!).
Let’s go step by step.
---
Part 1: Find the place value of digit 7
a.
6 725
Digits: 6 (thousands),
7 (hundreds), 2 (tens), 5 (ones)
→ 7 is in the
hundreds place → place value =
700
b.
15 987
Digits: 1 (ten-thousands), 5 (thousands), 9 (hundreds), 8 (tens),
7 (ones)
→ 7 is in the
ones place → place value =
7
c.
137 691
Digits: 1 (hundred-thousands), 3 (ten-thousands),
7 (thousands), 6 (hundreds), 9 (tens), 1 (ones)
→ 7 is in the
thousands place → place value =
7 000
d.
4 785 613
Break it down:
4 (millions),
7 (hundred-thousands), 8 (ten-thousands), 5 (thousands), 6 (hundreds), 1 (tens), 3 (ones)
→ 7 is in the
hundred-thousands place → place value =
700 000
e.
7 536 844
7 (millions), 5 (hundred-thousands), 3 (ten-thousands), etc.
→ 7 is in the
millions place → place value =
7 000 000
f.
1 474 123
1 (millions), 4 (hundred-thousands),
7 (ten-thousands), 4 (thousands), 1 (hundreds), 2 (tens), 3 (ones)
→ 7 is in the
ten-thousands place → place value =
70 000
---
Part 2: Find the value of digit 9
Note: The question says “value”, but from context and standard math practice for this grade level, it still means
place value (i.e., what the digit is worth in that position). So we do the same.
a.
9 622
9 is in the
thousands place → value =
9 000
b.
190 553
Digits: 1 (hundred-thousands),
9 (ten-thousands), 0 (thousands), 5 (hundreds), 5 (tens), 3 (ones)
→ 9 is in the
ten-thousands place → value =
90 000
c.
900 752
9 is in the
hundred-thousands place → value =
900 000
d.
9 685 148
9 is in the
millions place → value =
9 000 000
e.
5 754 925
Let’s write positions:
5 (millions), 7 (hundred-thousands), 5 (ten-thousands), 4 (thousands),
9 (hundreds), 2 (tens), 5 (ones)
→ 9 is in the
hundreds place → value =
900
f.
63 589
Digits: 6 (ten-thousands), 3 (thousands), 5 (hundreds), 8 (tens),
9 (ones)
→ 9 is in the
ones place → value =
9
Now double-check all:
Part 1:
a. 700
b. 7
c. 7 000
d. 700 000
e. 7 000 000
f. 70 000
Part 2:
a. 9 000
b. 90 000
c. 900 000
d. 9 000 000
e. 900
f. 9
All correct.
Final Answer:
1. a. 700
b. 7
c. 7 000
d. 700 000
e. 7 000 000
f. 70 000
2. a. 9 000
b. 90 000
c. 900 000
d. 9 000 000
e. 900
f. 9
