What is 47 rounded to the nearest ten?
47
40
50
45
To round to the nearest ten, look at the ones digit. Since 7 is 5 or greater, you round the tens digit up from 4 to 5, making 50. This follows the standard rounding rule when a digit is 5 or higher.
Round 6.78 to the nearest whole number.
7
6
6.7
6.8
When rounding to the nearest whole number, consider the first decimal place. Since .78 is .5 or more, you round up the whole number from 6 to 7. This is the basic rule for rounding decimals to integers.
Round 0.349 to the nearest hundredth.
0.35
0.34
0.33
0.3
To round to the nearest hundredth, look at the thousandths digit, which is 9. Since 9 is greater than or equal to 5, you round the hundredths place up from 4 to 5, giving 0.35. This follows standard decimal rounding rules.
What is 123 rounded to the nearest hundred?
100
200
150
110
When rounding to the nearest hundred, check the tens digit (2 in 123). Since 2 is less than 5, you round down the hundreds digit, leaving 1 as it is and zeros in the smaller places, making 100.
Round 4,675 to the nearest thousand.
4,500
5,000
4,700
4,000
To round to the nearest thousand, consider the hundreds digit (6 in 4,675). Since 6 is at least 5, you round the thousands digit up from 4 to 5 and replace smaller digits with zeros, yielding 5,000.
Round 8.725 to the nearest hundredth.
8.72
8.8
8.7
8.73
To find the nearest hundredth, inspect the thousandths digit, which is 5. Since it's 5 or more, increase the hundredths place from 2 to 3, making 8.73. This is a standard rounding approach for decimals.
Round -2.34 to the nearest whole number.
-3.0
-2
-3
-2.3
When rounding a negative decimal to the nearest whole number, you look at the first decimal digit. Since .34 is less than .5, the value is rounded toward zero, changing -2.34 to -2.
Round 0.0459 to the nearest thousandth.
0.045
0.05
0.046
0.047
To round to the nearest thousandth, check the ten-thousandths digit (9). Since it is greater than or equal to 5, increase the thousandths place from 5 to 6, giving 0.046.
Round 56,789 to the nearest hundred.
57,000
56,000
56,700
56,800
To round to the nearest hundred, examine the tens digit (8). Since it is at least 5, you round the hundreds digit from 7 to 8, making the result 56,800.
What is 9.999 rounded to the nearest tenth?
9.9
9.998
9.99
10.0
When rounding 9.999 to the nearest tenth, the hundredths digit (9) is 5 or more, so the tenth digit rounds up from 9 to 10, effectively giving 10.0. This is a demonstration of carrying over in decimal rounding.
Round 0.00049 to the nearest ten-thousandth.
0.0004
0.001
0.00049
0.0005
For the ten-thousandth place (four decimal places), look at the fifth decimal (9). Since it is 5 or greater, the fourth place increases from 4 to 5, yielding 0.0005.
What is 123,456 rounded to the nearest ten-thousand?
130,000
120,000
123,000
100,000
To round to the nearest ten-thousand, check the thousands digit (3). Since it is less than 5, the ten-thousand place remains 2 and the rest become zeros, making 120,000.
Round the value 1.41421356 (?2 approximation) to the nearest thousandth.
1.415
1.41
1.42
1.414
When rounding to the thousandth place, observe the ten-thousandth digit (2). Because it is less than 5, the thousandth digit stays at 4, giving 1.414.
A measurement reads 0.004659. What is this value rounded to three significant figures?
0.00465
0.005
0.00466
0.0047
For significant figures, start counting from the first non-zero digit. The first three are 4, 6, and 5, and the next digit is 9, which rounds the third digit up from 5 to 6, resulting in 0.00466.

Cheat Sheet

  1. Master the Standard "Half-Up" Rule -

    According to the National Council of Teachers of Mathematics (NCTM), the most common approach is the "half-up" rule: if the digit to the right is 5 or greater, round the target digit up; otherwise, keep it the same. For example, 3.76 rounds to 3.8 and 4.32 remains 4.3. Memorize "5 and up, give it a lift; 4 and down, let it sit" to recall this quickly.

  2. Identify and Leverage Place Value -

    Experts at the University of Cambridge emphasize pinpointing the target place value (ones, tenths, hundredths) before rounding. A handy mnemonic is "Locate, Look, Lift or Let" to guide you: locate the digit, look at the next, and lift up or let it stay. Practice with numbers like 58.49 to the nearest ten (rounds to 60) to build confidence.

  3. Differentiate Whole Number and Decimal Rounding -

    Khan Academy highlights that decimals rounding quiz strategies differ slightly: you're focusing on decimal places rather than integer positions. For instance, rounding 7.246 to two decimal places gives 7.25 because the third decimal (6) pushes the second up. Knowing both contexts prevents mix-ups on a math rounding test.

  4. Avoid Cumulative Rounding Errors -

    Research in the Journal of Mathematical Behavior warns against rounding at each step in multi-step problems to prevent drift in results. Instead, keep full precision until your final answer, then apply rounding rules once. This tip is crucial for accuracy in financial calculations and scientific data.

  5. Use Targeted Rounding Practice -

    Effective round numbers practice comes from consistent quizzes: try a free rounding quiz or a decimals rounding quiz weekly to reinforce skills. According to Edutopia, short, timed drills build speed and number sense, making your next rounding numbers quiz feel like a breeze. Track progress over time to boost both accuracy and confidence.
