Answer to the question meaning and actual situation:

29 10=2×3×5×97

As Huayu is a primary school student, his age is usually between 7 and 12 years old, so we can know that Huayu's age can be multiplied by 2 and 5 in the prime factor, which is 2× 5 = 10 (year). At this time, the above decomposition formula can be written as 29 10 = 10× 3× 97.

According to Huayu, 29 10 in this equation is the product of "ranking × age× score", so the answer to the question is: Huayu won the third place in this competition with 97 points.
