• Whole Number:

Nearest whole number - 24,689 is between 24,689 & 24,690, since I am rounding to the nearest whole number I will look at the tenths place to choose if I would round up or down. Since 4 is lower than 5 I would be rounding down. Which the answer is 24,689.

Nearest ten thousands - 24,689 in the ten thousands place is between 20,000 and 30,000, since 4 is lower than 5 I would be rounding down to 20,000.

• Tenths

Nearest tenths - I look at the 6 which is the tenths place, and look to the right number which is 7 I replace 7 as 0, since 7 is higher than 5 It would be 24,689.80.

• Nearest hundreds -  24,689.475 is between 24,600 & 24,700. Since I’m rounding up to the nearest hundreds I must look in the tenths place to decide if I need to round up or down. Because 8 is bigger than 5 I must round up to 24,700.

• I look at the 6 which is in the hundreds place and look at to the right and change 8 & 9 into 0s. So it would be 24,600 & 24,700, since 6 is higher than 5 I would be rounding down.

• Hundreths

Nearest hundreths -  I look at the 7 which is the hundredths place, and look at the right which is 5 I replace 5 as a 0, since 5 equal to 5 I round down. The answer is 24,689.470.
