The first column to the right of the decimal point is the tenths column. The second column to the right of the decimal point is the hundredths column. The third column to the right of the decimal point is the thousandths column. When rounding to the nearest tenth, you look at the digits in the hundredth and thousandths columns. The digit in the thousandths column is simply dropped. If the digit in the hundredths column is a 1 or 2 or 3 or 4, the digit is simply dropped, but if it is a 5 or 6 or 7 or 8 or 9, then it is dropped and the digit in the tenths column is increased by 1.
For 6.132 The 2 is dropped. The 3 is dropped. Answer: 6.1
For 8.976 The 6 is dropped. The 7 is dropped and the 9 is increased by 1 tenth which causes the 1's digit to be increased. Answer: 9.0
For each problem you will need to round the given number to the nearest tenth. Strive for accuracy and then strive to increase your speed. Good luck and enjoy the challenge!
