Final answer:
Using the provided information of feet and heads, it can be determined that the ratio of boys to girls in Ms. Wilson's class is 1:1, since there are an equal number of feet attributed to both boys and girls.
Step-by-step explanation:
The question involves finding the ratio of boys to girls in Ms. Wilson's class using the given information about feet and heads. We know that each person has one head and two feet. Since there are 8 feet and 4 heads in total, it means that there are 4 people in the class, as each person must have one head. Now, since 4 feet belong to boys and 4 feet belong to girls, it is clear that 2 boys and 2 girls are in the class, because 2 feet correspond to each boy and girl. Therefore, the ratio of boys to girls is 1:1.
