Some campers went rowing in the morning while 7 campers went rowing in the afternoon. If a total of 60 campers went rowing that day how many campers went rowing in the morning?
First, we need to find the total number of campers who went rowing in the morning and in the afternoon. 60 campers went rowing that day, so the total number of campers who went rowing in the morning and in the afternoon is 60. 

Next, we need to find the number of campers who went rowing in the afternoon. 7 campers went rowing in the afternoon, so the number of campers who went rowing in the afternoon is 7. 

Now, we need to find the number of campers who went rowing in the morning. The total number of campers who went rowing in the morning and in the afternoon is 60 and the number of campers who went rowing in the afternoon is 7, so the number of campers who went rowing in the morning is 60 - 7, which is the same as 53. 

Therefore the answer (numeric) is: 

53
