1.	55% of students in a school are boys.What is the ratio of boys to girls?How many boys and girls are there if the school has 800 students?
Answer» ANSWER: Ratio = 11:9 Boys = 440 Girls = 360 Step-by-step 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 × 800 => No. of boys = 55 × 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)/(40×9) => Ratio = 11/9 Hence, the ratio of boys to girls is 11:9 and number of boys and girls is 440 and 360 respectively.

Answer»

Ratio = 11:9

Boys = 440

Girls = 360

Step-by-step 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 × 800

=> No. of boys = 55 × 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)/(40×9)

=> Ratio = 11/9

Hence, the ratio of boys to girls is 11:9 and number of boys and girls is 440 and 360 respectively.
