Since 6 is in the tens place for both numbers, we compare the ones place. 8 in the ones place of 68 is greater than 2 in the ones place of 62, so 68 is greater than 62.
The digits in the tens place are the same (4), so we look at the ones place. Since 3 in the ones place of 43 is less than 8 in the ones place of 48, 43 is less than 48.
