Look above. Which digit is the tenths digit? The 9, the 4, or the 5?

- anonymous

9

- stevetron

5 or more go up 4 or less stay the same

- mathstudent55

Correct.
Since we are rounding tot eh nearest tenth, we must keep the 9.

- stevetron

the 9 is!!!

- anonymous

sorry i writeing another q

- stevetron

its 81

- anonymous

ok thanks

- mathstudent55

Since the digit after the 9 is 4, and 4 is from 0 to 4, the previous digit (the 9) does not go up by 1, so the 9 stays as 9.

i am confused who do i listen to?

- stevetron

i guess him

- Vocaloid

80.9 is correct
"round to the nearest tenth" means look at the tenths digit, then look at the digit right after it to decide where to round

@katieloveslife
I hate to do this, but look in my profile, and see if you can trust my answer.

- stevetron

i still think 81

- stevetron

ok go with his answer

- mathstudent55

81 is rounded to the nearest unit, or one.
The question is round to the nearest tenth, not nearest one.

- stevetron

ok

- anonymous

ok

- anonymous

one more?

- mathstudent55

sure

round the nearest number to the thousandths place 64,672.318498?

- anonymous

@Zedditup

- mathstudent55

Once again, the first step is to determine which digit is in the thousandths place.

- mathstudent55

64,672.318498
^
ten thousands place
64,672.318498
^
thousands place
64,672.318498
^
hundreds place

- anonymous

???????????????????????????
i dont know this one.

- mathstudent55

64,672.318498
^
tens place
64,672.318498
^
ones place
64,672.318498
^
tenths place

- mathstudent55

64,672.318498
^
hundredths place
64,672.318498
^
thousandths place

- anonymous

8

- anonymous

So it would be 81

- mathstudent55

To figure out what place a digit is, always start at the digit just to the left of the decimal point. That is always the ones digit.

- anonymous

so is it 9?

- anonymous

no it would be 81 im pretty sure

- mathstudent55

Then each digit to the right is 10 times smaller, tenths, hundredths, thousandths, etc.
Each digit tot eh left of the one place is 10 times larger, tens, hundreds, thousands, etc.

- anonymous

what do metals do?

- mathstudent55

|dw:1438108482645:dw|

- mathstudent55

We need the thousandths digit, so we go to the right one digit at a time.

- mathstudent55

|dw:1438108557959:dw|

- anonymous

ok

- mathstudent55

Now we know the 8 is the thousandths place.
Since we are rounding tot he nearest thousandth, we get rid of everything to the right of the thousandths digit.

- mathstudent55

|dw:1438108668934:dw|

- mathstudent55

We look at the first digit to the right of the 8.
It was a 4. Since 4 is from 0 to 4, we do not add 1 to the 8, so the final answer is:
|dw:1438108746655:dw|
