Let’s solve this step by step.
---
Problem 1: Identify the PLACE VALUE of the digit 7 in each number.
Place value tells us *where* a digit is sitting — like ones, tens, hundreds, thousands, etc.
We look at the position of the digit 7 in each number.
a.
6 725
→ The 7 is in the
hundreds place.
(6 = thousands, 7 = hundreds, 2 = tens, 5 = ones)
b.
15 987
→ The 7 is in the
ones place.
(1 = ten thousands, 5 = thousands, 9 = hundreds, 8 = tens, 7 = ones)
c.
137 691
→ The 7 is in the
thousands place.
(1 = hundred thousands, 3 = ten thousands, 7 = thousands, 6 = hundreds, 9 = tens, 1 = ones)
d.
4 785 613
→ The 7 is in the
hundred thousands place.
(4 = millions, 7 = hundred thousands, 8 = ten thousands, 5 = thousands, 6 = hundreds, 1 = tens, 3 = ones)
e.
7 536 844
→ The 7 is in the
millions place.
(7 = millions, 5 = hundred thousands, etc.)
f.
1 474 123
→ The 7 is in the
ten thousands place.
(1 = millions, 4 = hundred thousands, 7 = ten thousands, 4 = thousands, 1 = hundreds, 2 = tens, 3 = ones)
✔ So for Problem 1:
a. hundreds
b. ones
c. thousands
d. hundred thousands
e. millions
f. ten thousands

Problem 2: Identify the VALUE of the digit 9 in each number.
“Value” means how much the digit is worth based on its place.
So if 9 is in the hundreds place, its value is 900.
a.
9 622
→ 9 is in the
thousands place → value =
9,000
b.
190 553
→ 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
→ 9 is in the
hundreds place → value =
900
f.
63 589
→ 9 is in the
ones place → value =
9
✔ So for Problem 2:
a. 9,000
b. 90,000
c. 900,000
d. 9,000,000
e. 900
f. 9

Final Answer:
1. a. hundreds, b. ones, c. thousands, d. hundred thousands, e. millions, f. ten thousands
2. a. 9,000, b. 90,000, c. 900,000, d. 9,000,000, e. 900, f. 9
