It is 0.0005 or 5/10000 which is 1/2000 in its simplest form
Right most 5 (after the decimal) has a place value of 5/100 3 (after the decimal) has a place value of 3/10 Left most 5 (before the decimal) has a value of 5
It is 5.7 when rounded to one decimal place
Look at the third decimal place. If it is under 5 (as it is in this case), it rounds to .07. If the third decimal place was 5 or higher, it would round to .08.
There are not just 5 place values - there are infinitely many.

If the 3rd decimal place is 5 or more, increase the 2nd decimal place by 1, and discard everything after it. If the 3rd decimal place is less than 5, leave the 2nd decimal place alone, and discard everything after it.
Right most 5 (after the decimal) has a place value of 5/100 3 (after the decimal) has a place value of 3/10 Left most 5 (before the decimal) has a value of 5
It is 5.7 when rounded to one decimal place
The second decimal place is 5 or more, so the first decimal place increases by 1.69.6
The "units" place.
It is 4.1 when rounded to 1 decimal place
The '9' is in the "first decimal" place and the '3' is in the "second decimal" place.Rules for roundingIf the number in the second decimal place is 5 or greater then the number in the first decimal place is rounded upwards by 1.If the number in the second decimal place is 4 or less then the number in the first decimal place is left unchanged.As the problem in this case is 3.93 and the number in the second decimal place is less than 5, we end up with3.9 "correct to one decimal place" or "rounded to one decimal place".
It is a decimal because the fraction 3/5 when converted into a decimal is 0.6. The denominator is the decimal's place and the numerator is the number. 5 x 2 = 10 for the tenths place and 3x2 is 6 for the number.
When you round to 2 decimal places you will take the decimal portion which is .575 and look at the 3rd decimal place to the right which is 5. If this number is 5 or above you will round the second decimal place up 1 and if it is less than 5 you will keep it how it is. So in your case you will round the 7 up one because the 3rd place is 5 or above. Your answer will be 684.58 Hope this helps :)
The whole number is 5 and .267 is the decimal place value to three decimal places
Go to the second decimal place; if it is less than 5; round down. If it is 5 or greater, round up. So, 1.51 rounded to 1 decimal place is 1.5.
Look at the third decimal place. If it is under 5 (as it is in this case), it rounds to .07. If the third decimal place was 5 or higher, it would round to .08.
