Answer :
To solve the problem of finding the total number of students in all of the other grades, we first need to understand what the question is asking.
The school has a total of 764 students. Out of these, 118 students are in third grade. We want to find out how many students are in the other grades, which we will represent with [tex]\( s \)[/tex].
Here's how we can break it down step-by-step:
1. Start with the total number of students, which is 764.
2. Subtract the number of third-grade students, which is 118.
3. The difference will represent the number of students in all the other grades (denoted by [tex]\( s \)[/tex]).
So, the equation to find the number of students in all other grades is:
[tex]\[ 118 + s = 764 \][/tex]
To solve for [tex]\( s \)[/tex], subtract 118 from both sides of the equation:
[tex]\[ s = 764 - 118 \][/tex]
When you perform this subtraction, you get:
[tex]\[ s = 646 \][/tex]
This means there are 646 students in all other grades.
