First add 8 and 9 to get 17. Then divide 340 by 17 to get 20. Then times 20 by 8 to find the number of girls or times 20 by 9 to get the number of boys.
Number of girls: 160
Number of boys: 180
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 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
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.
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.
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
If there are 24 girls in a class of 50 and we assume the remaining students are boys, then there are 26 boys and the ratio of boys to girls is 26boys/24girls = 13/12=1.08333 boys for each girl.
18 boys and 12 girls
62.5
13 to 17
There are 1007 girls and 901 boys.
75. If the ratio is 3girl per 2boys. Then there's 45girls if there's 30boys...
