The total number of students in all other grades can be represented by the equation 118 + s = 764.
What is an equation?
'In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equal to sign.'
According to the given problem,
Total number of students = 764
Number of students in third grade = 118
Let s be the number of students in all other grades,
⇒ s + 118 = 764
⇒ s = 764 - 118
⇒ s = 646 students
Hence, we can conclude, the number of students in all other can be represented by the equation 118 + s = 764.
