To round 12.6257 to three decimal places, follow these steps:

1. Identify the digit at the third decimal place:
   In 12.6257, the third decimal place is 5.

2. Look at the digit in the fourth decimal place:
   The digit in the fourth decimal place is 7.

3. Decide whether to round up or down:

   • If the digit in the fourth decimal place is 5 or greater, round up the third decimal place.
   • If the digit in the fourth decimal place is less than 5, keep the third decimal place the same.

   Since the fourth decimal place is 7 (which is greater than 5), you round up the digit in the third decimal place.

4. Apply the rounding:

   • The third decimal place is 5, and rounding it up by 1 gives 6.

So, 12.6257 rounded to three decimal places is 12.626.

• 106.5 rounded to nearest whole number = 107.
• Since the digit after decimal is 5, the unit place is rounded by adding 1 to 6.

One curtain requires 250 cm of cloth.
25 curtains will require
= 25 × 250 = 6250 cm of cloth.
We know that 100 cm = 1 m.
Converting 6250 cm in meters we get
= 6250/100 = 62.50 m
∴ 25 curtain will require 62.50 m of cloth.
