Step-by-step explanation:
To find out how many kids in the boy scout troop wear glasses, we can use the formula: Number of kids wearing glasses = Total number of kids x Percentage of kids wearing glasses.
Given that there are 20 kids in the troop and 10% of them wear glasses, we can calculate:
Number of kids wearing glasses = 20 x 0.10 = 2
Therefore, 2 kids in the boy scout troop wear glasses.
