Answer:
Round to the nearest thousandth 1.2489 is 1.249
Solution:
Given number is 1.2489. We have to round to the nearest thousandth
Calculate the nearest thousand. In 1.2489, the nearest thousand is 8
Now, look one place to the right for the rounding digit. Hence we get “9” which is to the right of nearest thousandth “8”
Round up if this number is greater than or equal to 5 and round down if it is less than 5.
In 1.2489, the number “9” which is to right of nearest thousandth “8” is greater than 5. Hence we round off the nearest thousandth “8” to “9”
So 1.2489 when rounded off to nearest thousandth becomes 1.249
