Arranging the numbers in ascending and descending order

Arranging the numbers in ascending and descending order

The heights of five different apartments named as A, B, C, D, E in a locality are 985 feet, 1245 feet, 1865 feet, 355 feet, 585 feet respectively. They are shown according to their heights as shown in Fig. 1.1.

Can you arrange them in the ascending order of their heights?

We can arrange the numbers by comparing them based on the place values.

Step 1

Compare the 4 digit numbers 1245 and 1865. By following the steps mentioned for comparing the numbers having same number of digits, we get 1865 > 1245.

The tallest apartment is ‘C’ (1865 feet).

The next tallest apartment is ‘B’ (1245 feet)

Step 2

Compare the three digit numbers 985, 585 and 355. Using the Table 1.6, we get, 985 > 585 > 355. The smallest among them is 355.

Hence we write the heights of the apartments in ascending order as,

355 < 585 < 985 < 1245 < 1865

D          E        A         B            C
