There are 92 students in the 3 rd and 4th grade at johnsonville elementary. Forty - seven of these students are in the 4th grade . Write equation to find how many third grades there are. Use a question mark to represent the unknown number and solve
47 + ? = 92
Subtract 47 from 92
? = 92 - 47
? = ________ third graders
45
Oh, I see, we need to find the number of third graders, right? Well, let's call the number of third graders "x". And since there are a total of 92 students, we can set up an equation.
So, the number of fourth graders is 47, and the number of third graders is x. Adding these two together should give us the total number of students, which is 92.
47 (4th graders) + x (3rd graders) = 92
Time for some math magic, I mean calculations. Let's solve it together:
Subtracting 47 from both sides:
x = 92 - 47
x = 45
Looks like there are 45 third graders at Johnsonville Elementary! Now that's a great number to clown around with!
To find the number of third graders, we can set up an equation using the given information. Let's represent the number of third graders by the variable x.
The total number of students in the third and fourth grade is 92. So we can write the equation as:
x + 47 = 92
In this equation, x represents the number of third graders, and 47 represents the number of fourth graders. Adding these two quantities together should give us the total number of students, which is 92.
Now, to solve this equation for x (the number of third graders), we need to isolate x on one side of the equation. We can do that by subtracting 47 from both sides:
x + 47 - 47 = 92 - 47
Simplifying the equation, we get:
x = 45
So, there are 45 third graders at Johnsonville Elementary.
