The ratio of boys to girls in the 7th grade at GACA is 2 to 4. If there were 850 kids in the 7th grade, how many would you expect to be girls? Round to the nearest whole number
The total ratio of boys to girls is 2+4=<<2+4=6>>6
If we divide the total number of students (850) by the total ratio (6), we get 850/6=<<850/6=141.66666666666666>>141.67.
Rounding to the nearest whole number, we would expect there to be approximately 142 girls in the 7th grade at GACA.
Very close but not quite! These are the options:
213 girls out of 850 kids
425 girls out of 850 kids
567 girls out of 850 kids
607 girls out of 850 kids
To find the number of girls, we need to find the fraction of girls in the total ratio of 6 (2 for boys and 4 for girls).
The fraction representing girls is 4 out of 6, which simplifies to 2 out of 3.
To find the number of girls in the 7th grade, we multiply the fraction (2/3) by the total number of kids, 850.
(2/3) * 850 = 566.6666666666666
Rounding to the nearest whole number, we can expect approximately 567 girls out of 850 kids in the 7th grade.
Therefore, the correct answer is 567 girls out of 850 kids.
