Using all digits from 0 to 9 only once, form two fractions whose sum is 1.

Here are 2 examples:

[tex]\frac{1}{2} + \frac{4}{8}[/tex]

[tex]\frac{1}{2} + \frac{3}{6}[/tex]

Can you suggest a new one starting with [tex]\frac{2}{3}[/tex]

When you say "use digits 0 through 9 only once" I assume that means I can use NUMBERS formed from those digits as long as I only use a digit once. So, for example, 17 is fair game since I am only using the digits 1 and 7 once, whereas 44 woulnd't be allowed.

In that case it is quite simple: 2/3 + 6/18 = 1
