Using numbers from 1 to 9, express 1/2. You can't repeat any of the numbers and must use ALL of them (1,2,3,4,5,6,7,8,9). It also must be a whole number.

Example 1: 23/46 = 1/2. In this case I used 2,3,4 and 6 to express 1/2. So write the answer as a fraction but follow the above rules.

Example 2: No adding, you must do it list the fraction like this:
1467/59823 < I used all the numbers as you can see. This fraction expresses .024, but you must express 1/2. Basically, in the fraction ALL of the numbers must be present.

Show how you figured this out if possible (I already know the answer btw). You can guess&check if you want, but there are millions of guesses you will have to go through.

The present population, P, in thousands, of a town is related to the initial population of the town at time t = 0 by the formula

P = 125(3)^(0.05t)

where t is measured in years. The town was populated in 1880.

DON'T forget about the "in thousands" part.
