The 5th grade marching band includes boys & girls. There are 28 boys in a marching band. The boys are 7/10 of the students in the marching band. What fraction of students in the marching band girls? What is the total number of students in the marching band?

7/10 * kids=28 boys

kids in band= 280/7=40

girls? what is 1-7/10 ?

what is the answer please tell me

what does 7/10 mean

To find the fraction of girls in the marching band, we first need to calculate the fraction of boys in the marching band.

Given that there are 28 boys and they make up 7/10 of the students, we can set up the following equation:

28 = (7/10) * Total number of students

To solve for the total number of students, we need to isolate the variable:

Total number of students = 28 / (7/10)

To simplify, we can multiply by the reciprocal of 7/10 (which is 10/7):

Total number of students = 28 * (10/7)

Multiplying these values, we get:

Total number of students = 400/7

To find the fraction of girls in the marching band, we need to subtract the fraction of boys from 1. Since the boys make up 7/10 of the students, the fraction of girls would be:

Fraction of girls = 1 - 7/10

This can be simplified as:

Fraction of girls = 10/10 - 7/10

Fraction of girls = 3/10

Therefore, the fraction of girls in the marching band is 3/10 and the total number of students in the marching band is 400/7.
