Analysis:
To find the number of boys in the school, we first need to determine the total number of children in the school. We are given that 4/5 of the children are boys and the number of girls is 100.

Calculations:
Let's assume the total number of children in the school is 'x'.
Since 4/5 of the children are boys, the number of boys in the school = (4/5) * x
Given that the number of girls is 100, we can write the equation:
Number of girls = x - (4/5) * x
100 = x - (4/5) * x
100 = x - 4x/5
100 = 5x/5 - 4x/5
100 = (5x - 4x) / 5
100 = x / 5
x = 500
Therefore, the total number of children in the school is 500.

Final Answer:
To find the number of boys, we substitute the total number of children back into the equation:
Number of boys = (4/5) * 500 = 400
Therefore, there are 400 boys in the school.
