Explanation

To make a number close to 25, use 2 and 5 for the whole number part (25). Then arrange the remaining digits 1, 4, 8 in the decimal places to get as close to 25 as possible. Arranging them in ascending order gives the smallest decimal part, so 25.148 is the closest to 25.

Solution Steps

  1. Step 1: Use 2 and 5 for whole number: 25

  2. Step 2: Arrange remaining digits 1, 4, 8 in decimal places in ascending order

  3. Step 3: 25.148 uses all digits exactly once and is closest to 25
