Explanation:
We are given six sets of 2-digit numbers, and for each set, we need to write them in order from
greatest to
least, and also fill in the
tens and
ones digits for each number.
Let’s go one set at a time.
---
Set 1: 74, 30, 69, 93
- Compare the numbers:
- 93 is biggest (9 tens > 7, 6, 3)
- Next: 74 (7 tens)
- Then: 69 (6 tens)
- Smallest: 30 (3 tens)
So greatest → least:
93, 74, 69, 30
Now break each into tens and ones:
- 93 → Tens = 9, Ones = 3
- 74 → Tens = 7, Ones = 4
- 69 → Tens = 6, Ones = 9
- 30 → Tens = 3, Ones = 0

Set 2: 88, 34, 37, 53
Compare:
- 88 (8 tens) → largest
- 53 (5 tens)
- 37 and 34 both have 3 tens → compare ones: 7 > 4, so 37 > 34
Order:
88, 53, 37, 34
Tens/Ones:
- 88 → 8, 8
- 53 → 5, 3
- 37 → 3, 7
- 34 → 3, 4

Set 3: 19, 20, 61, 91, 83
Compare tens:
- 91 (9 tens) → largest
- 83 (8 tens)
- 61 (6 tens)
- 20 (2 tens)
- 19 (1 ten) → smallest
Order:
91, 83, 61, 20, 19
Tens/Ones:
- 91 → 9, 1
- 83 → 8, 3
- 61 → 6, 1
- 20 → 2, 0
- 19 → 1, 9

Set 4: 45, 74, 32, 26, 76
Tens:
- 76 and 74 both have 7 tens → compare ones: 6 > 4 → 76 > 74
- 45 (4 tens)
- 32 (3 tens)
- 26 (2 tens)
Order:
76, 74, 45, 32, 26
Tens/Ones:
- 76 → 7, 6
- 74 → 7, 4
- 45 → 4, 5
- 32 → 3, 2
- 26 → 2, 6

Set 5: 59, 12, 97, 42, 71
Tens:
- 97 (9 tens) → largest
- 71 (7 tens)
- 59 (5 tens)
- 42 (4 tens)
- 12 (1 ten) → smallest
Order:
97, 71, 59, 42, 12
Tens/Ones:
- 97 → 9, 7
- 71 → 7, 1
- 59 → 5, 9
- 42 → 4, 2
- 12 → 1, 2
---
Set 6: 90, 88, 91, 64, 85
Tens:
- 91 and 90 both have 9 tens → compare ones: 1 > 0 → 91 > 90
- 88 and 85 both have 8 tens → 8 > 5 → 88 > 85
- 64 (6 tens)
Order:
91, 90, 88, 85, 64
Tens/Ones:
- 91 → 9, 1
- 90 → 9, 0
- 88 → 8, 8
- 85 → 8, 5
- 64 → 6, 4
Let me double-check all orders:
1) 93 > 74 > 69 > 30
✔
2) 88 > 53 > 37 > 34
✔
3) 91 > 83 > 61 > 20 > 19
✔
4) 76 > 74 > 45 > 32 > 26
✔
5) 97 > 71 > 59 > 42 > 12
✔
6) 91 > 90 > 88 > 85 > 64
✔
All correct.
Final Answer:
1) Greatest: 93, 74, 69, 30 → Tens/Ones: (9,3), (7,4), (6,9), (3,0)
2) Greatest: 88, 53, 37, 34 → (8,8), (5,3), (3,7), (3,4)
3) Greatest: 91, 83, 61, 20, 19 → (9,1), (8,3), (6,1), (2,0), (1,9)
4) Greatest: 76, 74, 45, 32, 26 → (7,6), (7,4), (4,5), (3,2), (2,6)
5) Greatest: 97, 71, 59, 42, 12 → (9,7), (7,1), (5,9), (4,2), (1,2)
6) Greatest: 91, 90, 88, 85, 64 → (9,1), (9,0), (8,8), (8,5), (6,4)
