To find the number of boys in Mandy's school, we first need to express the ratio of boys to girls (1720) in a simplified form. The ratio can be interpreted as 17 boys for every 20 students (17 boys + 3 girls = 20 students). To find the number of boys, we can set up the equation: ( \text{Total students} = \text{boys} + \text{girls} ). Let ( x ) represent the number of boys; then ( x + \frac{3}{17}x = 1300 ). Solving this gives us approximately 780 boys in the school.
To find the number of boys in the school, we first need to determine the total number of parts in the ratio, which is 85 (girls) + 1 (boys) = 86 parts. Then, we divide the total number of students by the total parts in the ratio: 221 students / 86 parts = 2.57 students per part. Since we can't have a fraction of a student, we round down to the nearest whole number, which means there are 2 boys in the school.

1515 girls
There would be 6 boy students and 18 girl students in the class.
To find the ratio of the number of girls in the band to the total number of students, first calculate the total number of students: 17 boys + 12 girls = 29 students. The ratio of girls to the total number of students is 12 girls to 29 students, which can be expressed as 12:29.
50 students
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11

total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
Well, if the ratio of boys to girls is 4 to 3, that means there are 4 parts boys and 3 parts girls out of a total of 7 parts. So, the boys make up 4/7 of the total students, and the girls make up 3/7. With 910 students, that means there are 520 boys and 390 girls. So, there are 130 more boys than girls in the school.

There are 1007 girls and 901 boys.
75. If the ratio is 3girl per 2boys. Then there's 45girls if there's 30boys...
