Answer :
To find the middle number between 151800 and 112200, we need to calculate the average of these two numbers. The middle number can be found using the formula for the average of two numbers:
[tex]\text{Middle Number} = \frac{\text{First Number} + \text{Second Number}}{2}[/tex]
In this case:
[tex]\text{Middle Number} = \frac{151800 + 112200}{2}[/tex]
Step by step calculation:
Add the two numbers together:
[tex]151800 + 112200 = 264000[/tex]
Divide the sum by 2 to find the average:
[tex]\frac{264000}{2} = 132000[/tex]
Therefore, the middle number between 151800 and 112200 is 132000.
