9/14 = x/1050
Cross multiply and solve for x.
Number of boys = (9×1050)/(9+5) = 675
To find the number of boys in the school, you can first determine the total number of parts in the ratio. In this case, the total number of parts is 9 + 5 = 14.
Next, divide the total number of students (1050) by the total number of parts (14) to find the value of one part. 1050 divided by 14 equals 75.
Since the ratio of boys to girls is 9:5, you can multiply the value of one part (75) by the number of parts representing boys (9) to find the number of boys in the school. 75 multiplied by 9 equals 675.
Therefore, there are 675 boys in the school.
