To solve this question, we need to compare pairs of numbers and determine which is greater, lesser, or if they are equal. Here's how you can look at each comparison step-by-step:
390 vs 309 :
First, compare the hundreds digits: 3 (in 390) and 3 (in 309) are equal.
Check the tens digits: 9 (in 390) is greater than 0 (in 309).
Therefore, 390 > 309.
311 vs 321 :
Compare the hundreds digits: 3 (in 311) and 3 (in 321) are equal.
Look at the tens digits: 1 (in 311) is less than 2 (in 321).
Therefore, 311 < 321.
399 vs 398 :
Compare the hundreds digits: 3 (in 399) and 3 (in 398) are equal.
Check the tens digits: 9 (in 399) and 9 (in 398) are equal.
Finally, compare the units digits: 9 (in 399) is greater than 8 (in 398).
Therefore, 399 > 398.
340 vs 350 :
Compare the hundreds digits: 3 (in 340) and 3 (in 350) are equal.
Examine the tens digits: 4 (in 340) is less than 5 (in 350).
Therefore, 340 < 350.
300 vs 300 :
Both numbers are identical.
Therefore, 300 = 300.
By carefully comparing each digit place starting from the leftmost (highest value) position, we can accurately determine the relationship between each pair of numbers.
In summary, the comparisons are: 390 > 309, 311 < 321, 399 > 398, 340 < 350, and 300 = 300. Each comparison is based on examining the digits from the leftmost position. This method allows us to determine the relationship between each pair of numbers accurately.
