The cheerleading squad at Morristown High School had 10 members with the old coach. Now, with the new coach, there are 10% fewer members on the squad. How many members are on the squad now?
If the squad had 10 members with the old coach, 10*0.10 = <<10*0.10=1>>1 member has fewer now.
Since the number of members decreased by 1, the number of cheerleaders on the squad now is 10-1 = <<10-1=9>>9. Answer: \boxed{9}.
