Let’s go through each part step by step.
---
Part A: Write each set of numbers from the least to the greatest.
We need to sort each group of numbers in ascending order (smallest to largest).
a) 73, 78, 79, 76, 71
Look at the tens digit — all are 70s. So compare the ones:
71 < 73 < 76 < 78 < 79
→
71, 73, 76, 78, 79
b) 45, 25, 22, 30, 42
Compare all:
22 < 25 < 30 < 42 < 45
→
22, 25, 30, 42, 45
c) 52, 51, 56, 55, 57
All 50s → compare ones:
51 < 52 < 55 < 56 < 57
→
51, 52, 55, 56, 57
d) 17, 58, 51, 10, 15
Start with smallest: 10, then 15, 17, then 51, 58
→
10, 15, 17, 51, 58
e) 63, 45, 36, 29, 54
Order: 29 < 36 < 45 < 54 < 63
→
29, 36, 45, 54, 63
f) 94, 93, 91, 96, 87
87 is smallest, then 91, 93, 94, 96
→
87, 91, 93, 94, 96
---
Part B: Write each set of numbers from the greatest to the least.
Now we sort descending (largest to smallest).
a) 27, 44, 28, 48, 39
Largest: 48, then 44, 39, 28, 27
→
48, 44, 39, 28, 27
b) 79, 74, 72, 90, 75
90 is biggest, then 79, 75, 74, 72
→
90, 79, 75, 74, 72
c) 31, 32, 33, 35, 32
Note: two 32s. Order: 35 > 33 > 32 = 32 > 31
→
35, 33, 32, 32, 31
d) 86, 81, 83, 88, 85
88 > 86 > 85 > 83 > 81
→
88, 86, 85, 83, 81
e) 40, 49, 42, 46, 48
49 > 48 > 46 > 42 > 40
→
49, 48, 46, 42, 40
f) 88, 87, 85, 70, 71
88 > 87 > 85 > 71 > 70
→
88, 87, 85, 71, 70

Final Answer:
A)
a) 71, 73, 76, 78, 79
b) 22, 25, 30, 42, 45
c) 51, 52, 55, 56, 57
d) 10, 15, 17, 51, 58
e) 29, 36, 45, 54, 63
f) 87, 91, 93, 94, 96
B)
a) 48, 44, 39, 28, 27
b) 90, 79, 75, 74, 72
c) 35, 33, 32, 32, 31
d) 88, 86, 85, 83, 81
e) 49, 48, 46, 42, 40
f) 88, 87, 85, 71, 70
