### Instruction:
My mother celebrated her birthday with a total of 60 guests. Half of the guests are women, 15 are men, and the rest are children. In the middle of the celebration, 1/3 of the men and 5 children left. How many people stayed and enjoyed the birthday celebration?

### Response:
There were 60 guests / 2 = <<60/2=30>>30 women at my mother's birthday celebration.
There were 30 women + 15 men = <<30+15=45>>45 men and women at the birthday celebration.
There were 60 people - 45 men and women = <<60-45=15>>15 children at the birthday celebration.
15 men / 3 = <<15/3=5>>5 men left in the middle of the celebration.
There were 5 men + 5 children = 10 people who left in the middle of the celebration.
60 people - 10 people who left = 50 people stayed and enjoyed the birthday celebration.
