Answer:
Ratio = 11:9
Boys = 440
Girls = 360
Explanation:
Given that, in a school,
Total number of students = 800
Also,
Percent of boys = 55%
Therefore, number of boys = 55% of 800
No. of boys = 55/100 x 800
No. of boys = 55 x 8 =
No. of boys = 440
Therefore, we will get,
No. of girls = (800-440)
No. of girls = 360
Therefore, we will get,
Ratio of boys to girls = 440/360
Ratio = (40*11)/(40x9)
Ratio = 11/9
Hence, the ratio of boys to girls is 11:9 and number of boys and girls is 440 and 360 respectively.
