How does a number change when multiplied by 0.5? Give examples.

Multiplying 0.5 is the same as dividing a number by two, since 0.5 is equal to ½. For example: 12 * 0.5 = 6. Now consider it with the fraction 12 * ½ in order to solve it, you need to have two fractional numbers. Twelve is an integer and therefore we write it as the first twelve, now we multiply first the upper numbers 12 * 1 = 12, then the lower 1 * 2 and get twelve seconds. Since we have an integer number, we need to divide the upper number twelve by the lower two 12/2 = 6. This is how division by two is obtained when multiplied by 0.5 .
