Anna is making gingerbread cookies. She gives 6 of them red hats, 9 of them blue boots, and 3 of them both red hats and blue boots. What percentage of the gingerbread men have red hats?
The first step to find the total number of gingerbread men is to add the number with each decoration: 6 men + 9 men = <<6+9=15>>15 men
Then subtract the number of gingerbread men with both decorations to find the total number of gingerbread men: 15 men - 3 men = <<15-3=12>>12 men
Then divide the number of gingerbread men with red hats by the total number and multiply by 100% to express the answer as a percentage: 6 men / 12 men * 100% = 50%
