Answer:

$?+47=92$

The number of students in third grade 45

Step-by-step explanation:

Given : There are 92 students in the third and fourth grades at Johnsonville Elementary.

Of these, 47 are in fourth grade.

To Find : Write an equation to find how many third graders there are. Use a question mark to represent the unknown number and solve.

Solution:

Number of students in fourth grade = 47

Let ? be the number of students in third grade

So, total number of students = $?+47$

We are given that There are 92 students in the third and fourth grades

So, $?+47=92$

$?=92-47$

$?=45$

Hence an equation to find how many third graders there are is $?+47=92$ and the number of students in third grade is 45.
