Ratio of boys to girls in the seventh grade at GACA is 2 to 4 if there are 850 kids in the seventh grade how many would you expect to be girls round to the nearest whole number
The ratio of boys to girls in the seventh grade is 2 to 4, which can also be written as 2/4. To find the number of girls, we need to determine a fraction that represents the ratio of girls to the total number of students.
The total number of students is 850.
Let x be the number of girls. The fraction representing the ratio of girls to the total number of students is x/850.
The ratio of boys to girls is given as 2/4. This means that the fraction representing the ratio of boys to the total number of students is 2/4.
Since the ratio of boys to girls is equal to the ratio of the fractions representing the number of boys to the total number of students and the number of girls to the total number of students, we can set up the following equation:
2/4 = x/850
To solve for x, we can cross-multiply:
2 * 850 = 4 * x
1700 = 4x
Divide both sides by 4:
x = 1700/4
x = 425
Therefore, we would expect there to be approximately 425 girls in the seventh grade at GACA.
