A school has 764 students. Of the students, 118 are in third grade. Which equation can be used to find \( s \), the total number of students in all of the other grades?

A. \( s - 118 = 764 \)
B. \( 118 + s = 764 \)
C. \( s - 764 = 118 \)
D. \( 764 + 118 = 8 \)

Answer :

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.
