Look for lowest common multiple of 4 and 5
4, 8, 12, 16, 20
5, 10, 15, 20
In 20 days from December 20th she will wear both.
That would be January 9th

She wears the hat every 4 days and the jacket every 5 days.
We need to know when those will meet so we look at the multiples
of the numbers:
hat days after Dec 20: 4, 8, 12, 16, 20, ...
12/24, 12/28, 1/1, 1/5, 1/9
jkt days after Dec 20: 5, 10, 15, 20, ...
12/25, 12/30, 1/4, 1/9
How many days after December 20th will she be wearing both?
Answer is 20 days or January 9th
