In lowest terms, it is 4 to 3.
8:7
18 boys and 12 girls
In a class of 30, if there are 12 boys then there must be 18 girls. This would make the ratio: 18:12 or 3:2 (girls:boys)
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.
The ratio is 7 to 8

heya...... ratio is 30:70
2 to 3
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.
13 to 17
The ratio is 7 to 8
If there are four times as many boys as girls, then the ratio of boys to girls is 4:1. To find the number of girls, divide the total number of children by the sum of the parts of the ratio, which is 4+1. So, there would be 30/5 = 6 girls in the group.
the ratio is 3:5 what you do is make a fraction out of it (18/30) and then reduce and put a colon in it
80 boys and 30 girls
75. If the ratio is 3girl per 2boys. Then there's 45girls if there's 30boys...
