Question

Multiply 862.4 × 0.03

Answer 1

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
