Answer:
The answer to your question is boys = 250, girls = 450, total 700
Explanation:
Data
Ratio boys:girls 5:9
Number of boys = x
Number of girls = x + 200
Process
1.- Write the proportion
(5/9) = (x/ x +200)
- Solve for x
5(x + 200) = 9x
5x + 1000 = 9x
5x - 9x = -1000
- 4x = -1000
x = -1000/-4
x = 250
2.- Number of boys = 250
3.- Number of girls = 250 + 200
= 450
4.- Total number of students = 250 + 450
= 700
