1. Take any number, then divide it by 2 (in other words, half the number). If the result is whole, add a 0 at the end. If it is not, ignore the remainder and add a 5 at the end.
For example: 2462 x 5 =?
Step 1. 2462 / 2 = 1231
Step 2. Whole number, so add 0
The answer will be 2462 x 5 = 12310,
Example -2: Let’s try another: 3773 x 5
Step 1 3773 / 2 = 1886.5
Step 2. Fractional number, so ignore remainder and add 5
The answer will be 3773 x 5 = 18865
