Use the digits from 1 up to 9 and make 100.

Follow the rules.

=> Each digit should be used only once.

=> You can only use addition.

=> For making a number, two single digits can be combined (example, 4 and 2 can be combined to form 42 or 24)

=> A fraction can also be made by combining the two single digits (example, 4 and 2 can be combined to form 4/2 or 2/4)

Question: how can we do this ?

Will be update in one day
