7:2
To find the number of girls in the class, we can use the ratio of girls to boys, which is 5 to 2. This means for every 7 students (5 girls + 2 boys), there are 5 girls. To find the total number of groups of 7 in 49 students, we divide 49 by 7, giving us 7 groups. Therefore, the number of girls is 7 groups × 5 girls/group = 35 girls.
To simplify the ratio of 14 boys to 21 girls, you can divide both numbers by their greatest common divisor, which is 7. Dividing 14 by 7 gives you 2, and dividing 21 by 7 gives you 3. Therefore, the ratio of boys to girls in simplest form is 2:3.
Ex.) The ratio of boys to girls in the class was 7:5 (meaning there are 7 boys and 5 girls. If it was girls to boys it would be 5:7). Or you could write it as showed below: 7 to 5 7/5(as a fraction)
If the ratio of boys to girls is 3:7, this means that for every 3 boys, there are 7 girls. To find out how many boys there are, you would need to divide the total number of children by the sum of the parts in the ratio (3 + 7 = 10) and then multiply that result by the number of boys' parts in the ratio (3). So, if there are 30 children in total, there would be 9 boys (30 divided by 10, times 3).
It is already in its simplest ratio because 17 is a prime number but if it were 7 boys to 21 girls then the ratio would be 1 to 3
Using the ratio provided, since the ratio of girls to boys is 7 to 5, the total ratio can be calculated as 7 + 5 = 12. Since there are 275 boys, the number of girls can be calculated as (7/12) * (275) = 159.375, which rounds to 159 girls.
8 to 7.
To find the number of girls in the class, we can use the ratio of girls to boys, which is 5 to 2. This means for every 7 students (5 girls + 2 boys), there are 5 girls. To find the total number of groups of 7 in 49 students, we divide 49 by 7, giving us 7 groups. Therefore, the number of girls is 7 groups × 5 girls/group = 35 girls.
3+7=10 (3 and 7 are both ratio numbers) 420/10=42 (10 is the sum of both ratio) 3x42=126 girls (3 is ratio of girls) 7x42=294 boys (7 is ratio of boys)
To simplify the ratio of 14 boys to 21 girls, you can divide both numbers by their greatest common divisor, which is 7. Dividing 14 by 7 gives you 2, and dividing 21 by 7 gives you 3. Therefore, the ratio of boys to girls in simplest form is 2:3.
7:6 (girls to boys)
8:7
Ex.) The ratio of boys to girls in the class was 7:5 (meaning there are 7 boys and 5 girls. If it was girls to boys it would be 5:7). Or you could write it as showed below: 7 to 5 7/5(as a fraction)
A ratio of boys to girls was 3 to 7 and there were 200 more girls than boys there would of been 150 boys that enrolled in school this year. This is a math problem.
7/3 girls to boys.
If the ratio of boys to girls is 3:7, this means that for every 3 boys, there are 7 girls. To find out how many boys there are, you would need to divide the total number of children by the sum of the parts in the ratio (3 + 7 = 10) and then multiply that result by the number of boys' parts in the ratio (3). So, if there are 30 children in total, there would be 9 boys (30 divided by 10, times 3).
It is already in its simplest ratio because 17 is a prime number but if it were 7 boys to 21 girls then the ratio would be 1 to 3
