Rounding Numbers

Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274:

• Rounding to the nearest hundred is 800
• Rounding to the nearest ten is 840
• Rounding to the nearest one is 838
• Rounding to the nearest tenth is 838.3
• Rounding to the nearest hundredth is 838.27

Basic Rules of Rounding

When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:

• Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
• Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
• If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
• If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

Round to the Nearest Hundred: 3250

• Identify the hundreds digit: the 2 in 3250
• Identify the next smallest place value: the 5 in 3250
• Is that digit greater than or equal to five? Yes, so round up.
• Increase the hundreds digit by one, so 2 becomes 3. Every digit after becomes a zero.

3250 rounded to the nearest hundred is 3300

Round to the Nearest Ten: 323.5

• Identify the tens digit: the 2 in 323.5
• Identify the next smallest place value: the 3 in 323.5
• Is that digit greater than or equal to five? No, so round down.
• The tens digit stays the same at 2. Every digit after becomes a zero. Digits after the decimal point are dropped.

323.5 rounded to the nearest ten is 320

Round to the Nearest Ten: 499

• Identify the tens digit: the first 9 in 499
• Identify the next smallest place value: the second 9 in 499
• Is that digit greater than or equal to five? Yes, so round up.
• The tens digit increases by one. Since 9+1=10, you need to carry the 1 and add it to the digit in the hundreds place. Each digit after becomes a zero.

499 rounded to the nearest ten is 500

Round to the Nearest Tenth: 0.74

• Identify the tenths digit: 7 in 0.74
• Identify the next smallest place value: the 4 in 0.74
• Is that digit greater than or equal to five? No, so round down.
• The tenths digit stays the same at 7. Since the remaining digits are after the decimal point you just drop them.

0.74 rounded to the nearest tenth is 0.7

Round to the Nearest Hundredth: 3.141

• Identify the hundredths digit: the 4 in 3.141
• Identify the next smallest place value: the second 1 in 3.141
• Is that digit greater than or equal to five? No, so round down.
• The hundredths digit stays the same at 4. Drop the digits to the right of 4.

3.141 rounded to the nearest hundredth is 3.14

Math.com has several lessons on estimating and rounding.

Have you ever seen the directions, round to the nearest cent?" These directions are actually asking you to round to the nearest hundredth. Remember that the hundredths place is two moves from the right of the decimal point.

1.) 0.3493

- Underline the hundredths place 0.3493
- Look to the right.  0.3493
If it is 5 or above, we give it a shove. If it is 4 or below, we let it go.

- Round up to 0.35

- Underline the hundredths place 15.921978
- Look to the right.  15.921975 If it is 5 or above, we give it a shove.

If it is 4 or below, we let it go.

- Underline the hundredths place4,812.39812
- Look to the right. 4,812.39812
If it is 5 or above, we give it a shove. If it is 4 or below, we let it go.

In this example, it might be helpful to think of it as 39 rounding up to 40 instead of 9 rounding up to 10.

- Round to 4,812.40

4.) A dozen eggs costs $3.25. What is the cost of one egg?

0.2708333333.....

Each egg in the package costs about $0.27.

$8.48 ÷ 6 = $1.4133333333..... Again, we have a number that doesn't look like an amount that would show up on a register at the store. So we will round to the nearest penny or the nearest hundredth.

1.41333333333.........

we will keep the 1 and round to $1.41per pair of socks.
