Arithmetic

How to solve

Ignore the decimal points, multiply the whole numbers, then give the product as many decimal places as the two factors have combined.

Steps

  1. Multiply as if both factors were whole numbers.
  2. Count the total decimal places in the factors.
  3. Move the decimal point that many places left in the product.

Example

0.6 × 1.2

  1. 6 × 12 = 72.
  2. Two decimal places total → 0.72.

Answer: 0.72
