32-22=5 9-4=5
To solve the equation with the numbers 2, 9, 5, 9, and 4 to equal 22, you can use basic arithmetic operations. One possible solution is: ( 9 + 9 + 5 - 2 + 4 = 22 ). This combines addition and subtraction to reach the target number.
Assuming you are using "combinations" in the mathematical sense where order doesn't matter (if order does matter it would be "permutations"), there are 22C5 = 22!/5!17! = 26,334 possible combinations of 5 numbers from 22. They start {1, 2, 3, 4, 5}, {1, 2, 3, 4, 6}, {1, 2, 3, 4, 7}, ... and end ... {16, 19, 20, 21, 22}, {17, 19, 20, 21, 22}, {18, 19, 20, 21, 22}; I'll leave the 26,328 combinations in the middle for you to list.
5 and 11 are prime. The others are not (3 x 4 =12, 3 x 5 =15, 2 x 11 =22)
11 and 16 Because: 1+0 = 1 1+1 = 2 2+2 = 4 4+3 = 7 7+4 = 11 11+5 = 16 16+6 = 22 22+7 = 29 and so on ....
you add all of the numbers together, and then divide the sum by however many numbers there were. example: 2, 4, 4, 5, 7 2+4+4+5+7=22 22/5=4.4 average=4.4
32-22=5 9-4=5
4*5 + 6/3 = 20 + 2 = 22
there are 22
The LCM of 4 and 5 is 20, which is the multiple of the highest power of prime factors from both numbers (22 x 5 = 2 x 2 x 5 = 20).
Oh, dude, like, 1 and 220 go into 220. And, um, 2 and 110, and 4 and 55, and 5 and 44, and 10 and 22. So, yeah, those are the numbers that can slide into 220.

The reciprocal of the mixed number 4 2/5 is 5/22 The number 4 2/5 becomes (4 x 5) + 2 /5 = 22/5
