Worksheet-1: Arrange the numbers in descending order.

Problem Description:

The task is to arrange the given sets of numbers in descending order. Descending order means arranging the numbers from the largest to the smallest.

Solution Approach:

1. For each set of numbers, identify the largest number and place it first.
2. Identify the next largest number and place it second, and so on.
3. Continue this process until all numbers in the set are arranged in descending order.

Step-by-Step Solution:

#### (1) Numbers: \( 922, 259, 782, 777, 925 \)
- Largest: \( 925 \)
- Next largest: \( 922 \)
- Next largest: \( 782 \)
- Next largest: \( 777 \)
- Smallest: \( 259 \)

Descending Order: \( 925, 922, 782, 777, 259 \)

#### (2) Numbers: \( 521, 728, 399, 120, 478 \)
- Largest: \( 728 \)
- Next largest: \( 521 \)
- Next largest: \( 478 \)
- Next largest: \( 399 \)
- Smallest: \( 120 \)

Descending Order: \( 728, 521, 478, 399, 120 \)

#### (3) Numbers: \( 371, 632, 726, 488, 693 \)
- Largest: \( 726 \)
- Next largest: \( 693 \)
- Next largest: \( 632 \)
- Next largest: \( 488 \)
- Smallest: \( 371 \)

Descending Order: \( 726, 693, 632, 488, 371 \)

#### (4) Numbers: \( 505, 623, 323, 804, 137 \)
- Largest: \( 804 \)
- Next largest: \( 623 \)
- Next largest: \( 505 \)
- Next largest: \( 323 \)
- Smallest: \( 137 \)

Descending Order: \( 804, 623, 505, 323, 137 \)

#### (5) Numbers: \( 841, 208, 933, 896, 928 \)
- Largest: \( 933 \)
- Next largest: \( 928 \)
- Next largest: \( 896 \)
- Next largest: \( 841 \)
- Smallest: \( 208 \)

Descending Order: \( 933, 928, 896, 841, 208 \)

#### (6) Numbers: \( 269, 434, 335, 498, 765 \)
- Largest: \( 765 \)
- Next largest: \( 498 \)
- Next largest: \( 434 \)
- Next largest: \( 335 \)
- Smallest: \( 269 \)

Descending Order: \( 765, 498, 434, 335, 269 \)

#### (7) Numbers: \( 741, 899, 470, 630, 909 \)
- Largest: \( 909 \)
- Next largest: \( 899 \)
- Next largest: \( 741 \)
- Next largest: \( 630 \)
- Smallest: \( 470 \)

Descending Order: \( 909, 899, 741, 630, 470 \)

#### (8) Numbers: \( 258, 942, 873, 205, 979 \)
- Largest: \( 979 \)
- Next largest: \( 942 \)
- Next largest: \( 873 \)
- Next largest: \( 258 \)
- Smallest: \( 205 \)

Descending Order: \( 979, 942, 873, 258, 205 \)

#### (9) Numbers: \( 100, 463, 653, 777, 553 \)
- Largest: \( 777 \)
- Next largest: \( 653 \)
- Next largest: \( 553 \)
- Next largest: \( 463 \)
- Smallest: \( 100 \)

Descending Order: \( 777, 653, 553, 463, 100 \)

#### (10) Numbers: \( 520, 386, 166, 413, 468 \)
- Largest: \( 520 \)
- Next largest: \( 468 \)
- Next largest: \( 413 \)
- Next largest: \( 386 \)
- Smallest: \( 166 \)

Descending Order: \( 520, 468, 413, 386, 166 \)
