I thinks it is matching pairs for random assignment on gender, age, & income status but I’m not sure
For me cross multiplying works really well.
This would be True. For example. If your number is 24, and 'n' is 12 ( a factor of 24 )
your factors of 12 (12, 6, 4, 3, 2, 1) are also included in the factors of 24 (which are 24, 12, 6, 4, 3, 2, 1)
A) 0.5 would be the greater number out of them all.
