Question 208403
round to nearest 1000th   -0.3898

To the nearest thousandths means that we need to have this number to 3 decimal places.


As the fourth digit, 8, is greater than 5, we need to ROUND UP the previous digit, 9. However, this number when ROUND UP gives us 0, which means that we need to ROUND UP the next preceding digit which is 8.


This therefore makes this number {{{highlight_green(-0.390)}}}
