a class of 25 students has 10 boys. Three boys have braces and 4 girls have braces..what is the ratio of boys with braces to boys in class
ratio is 1:2 in other words for every 1 boy there are 2 girls
3:10
10:18 or 5:9 (simplified)
Expressed as a ratio in its simplest form, 10 boys to 25 girls are in the ratio 2:5.
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)
The ratio of girls to boys in this case would be 10:1
1 to 2 = 5 to 10 so 15 students in all.
Of the total 15 people 5 are boys and 10 are girls Boys are 5/15 = 1/3 Girls are 10/15 = 2/3 Ratio of boys to girls is 1 to 2
10 to 15 or 2 to 3 even
It is: 2 to 3
3 to 4 cuz you would do boys first since its first in the problem
