Answer:

1) 56.2671

In the above number, the 2 is in the tenths place, the 6 is in the hundredths place, and the 7 is in the thousandths place.  So:

tenths: 56.3  hundredths: 56.28  thousandths: 56.267

2) 8.4325

In the above number, the 4 is in the tenths place, the three is in the hundredths place, and the 2 is in the thousandths place.  So:

tenths: 8.4  hundredths: 8.43  thousandths: 8.433

Step-by-step explanation:

Place Values are assigned starting with the ones place which is the number immediately before the decimal point.  On the left side of the decimal point, moving left, you have ones, tens, hundreds, thousands; numbers get bigger moving in this direction.  Moving to the right, starting with the ones place, you have ones, tenths, hundredths, thousandths; numbers get smaller moving in this direction because they are all less than one.  Notice that the place values on the left of the decimal point have words that end in 's', and place values to the right of the decimal point have words that end in 'ths'.

When determining the rounded value, consider the number(s) to the right of the value you are rounding.  If the number to the right is 5 or more, then the value you are rounding increase by one.  If the number to the right is 5 or less, then the value you are rounding stays the same.  If a number reaches 10 while rounding, then the it becomes 0 and the number in front of it (to the left) increases by one.  (This is seen in 10.597  when rounding to the nearest hundredths; the 7 increases the 9 by one.  The 9 becomes a 10 so the 0 goes in the hundredths spot, and the 5 increases by one (just like carrying the one in addition).
