The ratio of boys to girls in the 7th grade at a school is 2 to 4. if there was 850 kids in the seventh grade, how many would you expect to be girls? Round to the nearest whole number.
A. 213 girls out of 850 kids
B. 425 girls out of 850 kids
C. 567 girls out of 850 kids
D. 607 girls out of 850 kids.
The ratio of boys to girls is 2 to 4 or simplified as 1 to 2. This means that for every 1 boy, there are 2 girls.
To find the number of girls, we divide the total number of kids (850) by the sum of the parts of the ratio (1 + 2 = 3).
Total number of girls = (2/3) * 850 = 567 girls
Therefore, the correct answer is C. 567 girls out of 850 kids.

Apologies for the mistake. Let's correct the calculation.
The ratio of boys to girls is 2 to 4, or 2/6 boys and 4/6 girls. This can be simplified to 1/3 boys and 2/3 girls.
To find the number of girls, we multiply the total number of kids (850) by the fraction representing girls in the ratio:
Total number of girls = (2/3) * 850 = 566.67
Rounding to the nearest whole number, we would expect approximately 567 girls out of 850 kids.
Therefore, the correct answer is C. 567 girls out of 850 kids.
