Number System Worksheet-1 for students to practice identifying greatest, smallest, and ascending order of numbers.

Let's solve each question step by step and explain the reasoning.

Section 1: Find the greatest number in each set

#### (1) 435, 453, 534
Compare the numbers:
- 435 vs 453 → 453 is greater (same hundreds, but 5 > 3 in tens)
- 453 vs 534 → 534 is greater (5 > 4 in hundreds)

✔ Answer: (B) 534

---

#### (2) 72, 207, 270
Compare:
- 72 is a two-digit number
- 207 and 270 are three-digit numbers → both are larger than 72
- 207 vs 270 → 270 is greater (same hundreds, 7 > 0 in tens)

✔ Answer: (C) 270

---

#### (3) 5934, 3954, 5943
Compare:
- 5934 vs 3954 → 5934 is greater (5 > 3 in thousands)
- 5934 vs 5943 → both have 59 in thousands and hundreds, compare tens: 3 vs 4 → 5943 is greater

✔ Answer: (C) 5943

---

#### (4) 78925, 86952, 88562
Compare:
- All are five-digit numbers
- Compare ten-thousands digit:
- 78925 → 7
- 86952 → 8
- 88562 → 8 → so 78925 is smallest
- Now compare 86952 and 88562:
- Thousands digit: 6 vs 8 → 88562 is greater

✔ Answer: (A) 88562

---

Section 2: Find the smallest number in each set

#### (5) 539, 362, 652
Compare:
- 362 < 539 < 652 → smallest is 362

✔ Answer: (B) 362

---

#### (6) 9652, 8953, 6589
Compare:
- 6589 has smallest thousands digit (6)
- 8953 → 8
- 9652 → 9 → so 6589 is smallest

✔ Answer: (B) 6589

---

#### (7) 10596, 1596, 196
Compare:
- 196 → 3-digit
- 1596 → 4-digit
- 10596 → 5-digit
- Smallest number of digits = smallest value → 196 is smallest

✔ Answer: (A) 196

---

#### (8) 5963, 5693, 569
Compare:
- 569 → 3-digit → smallest
- 5693 and 5963 → both 4-digit
- But 569 is clearly smaller than others

✔ Answer: (A) 569

---

Section 3: Find the series with ascending order

#### (9) Given numbers: 27, 856, 72, 963, 958

We need to arrange them in ascending order (smallest to largest):

Step-by-step:
- 27 (smallest)
- Then 72
- Then 856
- Then 958
- Then 963

So ascending order: 27, 72, 856, 958, 963

Now check options:

- (A) 963, 958, 856, 27, 72 → descending → ✘
- (B) 27, 72, 856, 963, 958 → 963 before 958 → wrong → ✘
- (C) 27, 72, 856, 958, 963 → correct → ✔

✔ Answer: (C)

🔍 Explanation Summary:

- To find the greatest or smallest, compare digits from left to right.
- Numbers with more digits are generally larger (unless comparing very close values).
- For ordering, list all numbers and sort them step by step.
