There are #70# students in total, of which #28# are girls.

In order to simulate the ratio of girls to boys, we first establish an algebraic relationship, with Thus #1/2 * g = 1/3 * b# We can enter the number of boys since we know it: #1/2 * g = #1/3 * 42# This connection reduces to #1/2 * g = 14# which ultimately reduces to #g = 14 * 2 = 28# Then, we can simply add the numbers of girls and boys to find the total number of students: #28 + 42 = 70# Therefore, there are #70# total students, of which #28# are girls and #42# are boys.

undefined To find the number of girls, first find the total number of students using the given ratio and the number of boys. Then, calculate the number of girls using the ratio of girls to boys.

Total number of students = Number of boys / (Ratio of boys to total students)
Total number of students = 42 / (3/2) = 42 * (2/3) = 28

Number of girls = Total number of students - Number of boys
Number of girls = 28 - 42 = 14

Total number of students = Number of girls + Number of boys
Total number of students = 14 + 42 = 56

If the ratio of girls to boys is 2:3 and there are 42 boys .find the number of girls and total number of students? This sum is of ratio and proportion.
