1. Comparison using Place Value: - When comparing numbers based on place value, we look at the value of each digit in the number. - For 378 and 379, the hundreds place is the same, and the tens and ones places are also the same. Therefore, we can say that 379 is greater than 378. - For 6572 and 986, the thousands place in 6572 is greater than the hundreds place in 986, so 6572 is greater than 986. - For 42375 and 39879, the ten thousands place in 42375 is greater than the three thousands place in 39879, so 42375 is greater than 39879.

2. Comparison using Addition: - Another method to compare numbers is to add 1 to the smaller number and compare the result with the larger number. - For 378 and 379, adding 1 to 378 gives 379, so 379 is greater than 378. - For 6572 and 986, adding 1 to 986 gives 987, which is less than 6572, so 6572 is greater than 986. - For 42375 and 39879, adding 1 to 39879 gives 39880, which is less than 42375, so 42375 is greater than 39879.

3. Comparison using Subtraction: - We can also compare numbers by subtracting one from the other and analyzing the result. - For 378 and 379, subtracting 378 from 379 gives 1, indicating that 379 is greater than 378. - For 6572 and 986, subtracting 986 from 6572 gives 5586, showing that 6572 is greater than 986. - For 42375 and 39879, subtracting 39879 from 42375 gives 2496, indicating that 42375 is greater than 39879.

4. Comparison using Multiplication: - Multiplying the numbers by a common factor can also help in comparison. - For 378 and 379, multiplying both by
