When we round a number to the thousandths place, we look to the ten thousandths place (the digit directly to the right of the thousandths place) to tell us if we round up or down. 

In this case, our ten thousandths place is \(\displaystyle 3\), which tells us to round down. Remember, \(\displaystyle 0-4\) means round down, \(\displaystyle 5-9\) means round up. 

The \(\displaystyle 6\) is in the thousandths place, so that stays \(\displaystyle 6\) and we get rid of all of the numbers to the right of the thousandths place. Our rounded number becomes \(\displaystyle 78.176\)

When we round a number to the thousanths place, we look to the ten thousandths place (the digit directly to the right of the tousandths place) to tell us if we round up or down. 

In this case, our ten thousanths place is \(\displaystyle 4\), which tells us to round down. Remember, \(\displaystyle 0-4\) means round down, \(\displaystyle 5-9\) means round up. 

The \(\displaystyle 9\) is in the thousandths place, so that stays at \(\displaystyle 9\) and we get rid of all of the numbers to the right of the thousandths place. Our rounded number becomes \(\displaystyle 56.789\). 

When we round a number to the tenths place, we look to the hundredths place (the digit directly to the right of the tenths place) to tell us if we round up or down. 

In this case, our hundredths place is \(\displaystyle 3\), which tells us to round down. Remember, \(\displaystyle 0-4\) means round down, \(\displaystyle 5-9\) means round up. 

The \(\displaystyle 6\) is in the tenths place, so we leave that as a \(\displaystyle 6\) and get rid of all of the numbers to the right of the tenths place. Our rounded number becomes \(\displaystyle 987.6\)

When we round a number to the hundredths place, we look to the thousandths place (the digit directly to the right of the hundredths place) to tell us if we round up or down. 

In this case, our thousandths place is \(\displaystyle 7\), which tells us to round up. Remember, \(\displaystyle 0-4\) means round down, \(\displaystyle 5-9\) means round up. 

The \(\displaystyle 6\) is in the hundredths place, so we round that up to \(\displaystyle 7\) and get rid of all of the numbers to the right of the hundredths place. Our rounded number becomes \(\displaystyle 23.17\)

When we round a number to the thousandths place, we look to the ten thousandths place (the digit directly to the right of the thousandths place) to tell us if we round up or down. 

In this case, our ten thousandths place is \(\displaystyle 5\), which tells us to round up. Remember, \(\displaystyle 0-4\) means round down, \(\displaystyle 5-9\) means round up. 

The \(\displaystyle 7\) is in the thousandths place, so we round that up to \(\displaystyle 8\) and we get rid of all of the numbers to the right of the thousandths place. Our rounded number becomes \(\displaystyle 45.788\)

When we round a number to the thousandths place, we look to the ten thousandths place (the digit directly to the right of the thousandths place) to tell us if we round upfor down.
