Salutations!
Round 392,153 to the nearest hundred thousand.
To round the number to the nearest hundred thousand, you need to check whether the number next ti hundred thousand is greater than 5 or lesser than 5. If its greater, you need to round up by adding plus one to the hundred thousand place. If its lesser than 5, you need to round down by adding zeros accordingly.
392, 153 ≈ 400, 000. (Round up).
Hope I helped (:
Have a great day!
