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)
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
boys:girls::7:9
49 boys!
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.
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.
7:6 (girls to boys)

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.
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
The ration of girls to boys is 21:6To simplify this divide both numbers by 3 = 7:2
