The Correct Answer and Explanation is:1
The correct number that goes in the box is 245.
To solve this problem, we need to find the missing value in the subtraction equation: 379 minus some number equals 134. This type of problem can be solved by understanding the relationship between the parts of a subtraction equation or by using simple algebra.
Let’s think about the equation: 379 – ☐ = 134. In this equation, 379 is the starting amount (the minuend), the number in the box is the amount being taken away (the subtrahend), and 134 is the result (the difference). The problem asks us to find the subtrahend.
One way to find the missing number is to rearrange the equation. If you start with 379 and end up with 134 after taking a number away, you can find out what number was taken away by subtracting the final amount from the starting amount. This means we need to calculate 379 minus 134.
We can perform this subtraction step by step, column by column:
- Ones column: Start with the rightmost digits. We calculate 9 minus 4, which equals 5.
- Tens column: Next, move to the middle digits. We calculate 7 minus 3, which equals 4.
- Hundreds column: Finally, look at the leftmost digits. We calculate 3 minus 1, which equals 2.
Putting these digits together from left to right (hundreds, tens, ones), we get the answer: 245.
To double check our work, we can place 245 back into the original box and see if the equation holds true:
379 – 245 = 134
Performing this subtraction, we find that 379 minus 245 is indeed 134. This confirms that 245 is the correct number to go in the box.
