Answer:
8 girls
Step-by-step explanation:
Number of girls = 11, while number of boys = 9.
Total number of children swimming in the pool = 17
Let us assume that all the boys and girls can swim, and the children are in the pool simultaneously.
Therefore, the least number of girls swimming in the pool would occur when all the boys are swimming in the pool.
Such that,
the least number of girls swimming = 17 - 9
= 8
The least number of girls swimming in the pool is 8.
