The ratio of boys to girls is 2 to 4, which can also be written as 1 to 2.
To find the number of girls, we need to divide the total number of kids (850) by the sum of the ratio parts (1 + 2), and then multiply by the ratio part representing girls (2).
Number of girls = (850 / (1 + 2)) * 2
Number of girls = (850 / 3) * 2
Number of girls β 566.67
Rounding to the nearest whole number, we would expect approximately 567 girls out of 850 kids.
The closest answer choice is "567 girls out of 850 kids".
