10 to 15 or 2 to 3 even
The ratio of girls to boys in this case would be 10:1
1 to 2 = 5 to 10 so 15 students in all.
3 to 4 cuz you would do boys first since its first in the problem
It is 10:3, as stated in the question!
B/G = 4/3 so 3B = 4G B+G = 21 Multiply by 3: 3B+3G = 63 But 3B = 4G so 4G+3G = 63 ie 7G = 63 so that G = 9 So B+G=21 means B = 12 3 more boys so B' = 12+3 = 15 1 more girl so G' = 9+1 = 10 So new ratio = B'/G' = 15/10 = 3/2 or 3 to 2
Expressed as a ratio in its simplest form, 10 boys to 25 girls are in the ratio 2:5.
The ratio is: 2 to 1
The ratio of girls to boys in this case would be 10:1
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
There are 10 students in the initial selection. (7+3) 3 is 30% of 10 and 7 is 70% of ten. 30% of 420 = 126 girls 70% of 420 = 294 boys There are 126 girls at the concert.
ratio is 1:2 in other words for every 1 boy there are 2 girls
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
for girls at 9 to 10 and boys 10 to 11
It is: 2 to 3
10:18 or 5:9 (simplified)
3:10
The ratio was estimated at 1046 to 1000 in 2013.
