Multiply 862.4 * 0.03

The answer in calculator is 25.872

The easiest way to do this, in my opinion, is to multiply by 3 and then divide it by a nice even 100 (since it's 3 hundreths)

862.4 * 3 =

3 * 4 = 12

carry the 1

863.2

3 * 3 = 9

869.2

6 * 3 = 18

carry the 1

989.2

9 * 3 = 27

carry the 2

and you have 2769.2

then you just move it over two decimal spaces to get

27.692

So, 862.4 * 0.03 = 27.692
