In a school the students ratio of boys : girls is 3:5
There are 450 boys.Work out the total number of students in the school ?
There are 450 boys.
Let the number of girls be x.
Therefore:
3/5 = 450/x
Cross multiply
3x = 2250
x = 750
There are 750 girls.
The total number of students:
450 + 750 = 1200
Answer:
1200
