Answer:
1000
Step-by-step explanation:
Let the total number of children in school be y.
Then according to the question (4/5) of children are boys.
Then as we know that the sum of fractions is 1.
The fraction of girls in school is
1 - (4/5)= (1/5)
So this means (1/5) of the total children in school are girls which means
Y × (1/5) =200 , according to question.
Which gives y =200×5=100
This means that the total number of children in school is 1000.
