hundredths is
6.7866845
To round a number to the nearest hundredths , look at the next place value to the right (the thousandths this time). Same deal: If it's 4 or less (4, 3, 2, 1, 0), just remove all the digits to the right (ex: 4.75018 = 4.75). If it's 5 or greater (5, 6, 7, 8, 9), add 1 to the digit in the hundredths place, and then remove all the digits to the right. (ex: 6.23923= 6.24)
