4 times 9 = 36
4 multiplied by 1/9 = 4/9
Well, 6 is not prime because 2 multiplied by 3 is 6 and 6 multiplied by 1 is 6. 4 is also not a prime because 2 multiplied by 2 is 4 and 4 multiplied by 1 is 4. 9 is also not a prime because 32 is 9 and 9 multiplied by 1 is 9. 2 is the only number left, so therefore 2 is the prime number of 6, 4, 2, and 9.

4 + 2 x 9 = 4 + 18 = 22
4/8 still because 9/9 is 1.
(7/9) x (4/63) = (1/9) x (4/9) = 4/81
4/9 x 1/2 is equal to 4/18 (2/9)
