4,897,542
.854

Round the numbers above to the……

Nearest thousands = 4,898,000
4,898,000 is between 4,898,000 and 4,899,000 Since i am rounding up to the nearest thousands I will look at the number in the tenths place to decide whether to round up or down.Because 5 is greater than 5 i will round up to  4,898,000

Nearest tenths = 4,897,542.900
4,898,000 is between 4,897,542.900 and 4,897,542.800 Since i am rounding up to the nearest tenths I will look at the number in the tenths place to decide whether to round up or down.Because 5 is greater than 5 i will round up to  4,898,000

Nearest ten thousands = 4,900,000
4,898,000 is between 4,900,000 and 5,000,000 Since i am rounding up to the nearest ten thousands I will look at the number in the tenths place to decide whether to round up or down.Because 9 is greater than 5 i will round up to  4,900,000

Nearest hundredths = 4,897,542.850
4,898,000 is between 4,897,542.850 and 4,897,542.860 Since i am rounding up to the nearest hundreths I will look at the number in the tenths place to decide whether to round up or down.Because 4 is less than 5 i will round down to  4,897,542.850

Nearest tens = 4,897,540
4,898,000 is between 4,897,540 and 4,897,550 Since i am rounding up to the nearest thousands I will look at the number in the tenths place to decide whether to round up or down.Because 4 is less than 5 i will round down to  4,897,540

Nearest whole number = 4,897,543.854
4,897, 543.854 is between 4,897,543.854 and 4,897,542.854 Since i am rounding up to the nearest thousands I will look at the number in the tenths place to decide whether to round up or down.Because 4 is less than 5 i will round down to 4,897,543.854

Nearest hundreds = 4,897,500

4,897, 543.854 is between 4,897,500 and 4,897,600 Since i am rounding up to the nearest thousands I will look at the number in the tenths place to decide whether to round up or down.Because 4 is less than 5 i will round down to  4,897,500
