There are total 77 students in the sixth grade.

Given, there are 28 students that have braces.

out of which there are 4 students with braces for every 7 students.

Therefore, 4 ₊ 7 = 11, which means every 11 member has 4 members with braces.

Therefore, based on the given conditions, formulate:

28 × (4 ₊ 7) ÷ 4

28 × 11 / 4

now cross out the common factors.

7 × ( 11)

multiply the above terms.

77

hence we get the answer as 77 students in total in the class.
