Required Mathematical Intelligence

Chapter 42
On the road, a man and a woman walked side by side.At first glance, they happened to both start with their right feet at the same time.Then, because the man's stride is large, the woman's 3 steps can keep up with the man's 2 steps.Let me ask, how many steps should the woman take from the time when both start with the right foot to the time when both of them step out with the left foot?

[Answer: Is this question a class of least common multiple?Many people will think of this point. The least common multiple of 3 and 2 is 6. Does it mean that the two walk with their left foot at the 6th step?No, it needs to be considered from the actual point of view, so that it is more clear at a glance, and it is impossible for men and women to step out with their left feet at the same time.You should exercise your leap from abstraction to reality, from reality to abstract thinking. ]
