The number of calligraphy activity groups is between 40 and 50. How many people are there in the calligraphy group if every six people or every eight people happen to be right?

6=2×3,8=2×2×2,

The least common multiple of 6 and 8 is 2× 2× 2× 3 = 24;

Because between 40 and 50, the number of calligraphy groups should be: 24×2=48 (people).

A: There are 48 people in the calligraphy group.
