There is 10 white,9 black and 7 red balls in a bucket,In how many ways we can select one or more balls?

Lets take an example. 4/5 if you mark 4 is less than 5. So when we start to convert, if thenumerator is smaller thanthe denominator, the fraction starts. I mean we start with 0.(period) Then we add a "0" to the numerator. So in our case, it will be now 40...

the best approach to solve this is find out the combinition that will make 23 e.g. 1+22, 2+21, 3+20,4+19, 5+18, 6+17, 7+16, 8+15, 9+14,10+13, 11+12. Then it repeats. Now lets evaluate which pair is prime. (Prime is a number which is divisible by 1 and by...

7/11, -8/6, -6/8, 9/4, 27/25
