how do you find the theoretical range of girl to boys in a class 2/5 to 1/5

Your school subject is MATH, not college.

you gotta divide by the # of boys and girls by 2/5 and 1/5

To find the theoretical range of girls to boys in a class, you need to determine the maximum and minimum values based on the given ratios.

The ratio 2/5 represents the number of girls to the total number of students, while the ratio 1/5 represents the number of boys to the total number of students in the class.

Let's assume the total number of students in the class is 'T'.

To find the maximum number of girls, you need to multiply the given ratio of 2/5 by the total number of students:

Maximum number of girls = (2/5) * T

Similarly, to find the maximum number of boys, you multiply the given ratio of 1/5 by the total number of students:

Maximum number of boys = (1/5) * T

To find the minimum number, we need to consider the opposite ratio. So, the minimum number of girls is determined by multiplying the given ratio of 1/5 by the total number of students:

Minimum number of girls = (1/5) * T

And the minimum number of boys can be calculated by multiplying the given ratio of 2/5 by the total number of students:

Minimum number of boys = (2/5) * T

Therefore, the theoretical range of girls to boys in the class is from the minimum number of girls to the maximum number of girls, and the same goes for boys.
