Which number will have the same result, when rounded to the nearest ten or hundred? Is it 97, 118 and 5, 179 or 5,091?
97 rounded to nearest ten gives 100
97 rounded to nearest hundred gives 100
118 rounded to nearest ten gives 120
118 rounded to nearest hunted gives 100
5 rounds to nearest ten is 10
179 rounded to nearest ten gives 180
179 rounded to nearest hundred gives 200
5091 rounded to nearest ten gives 5090
5091 rounded to nearest hundred gives 5100
So clearly the answer is 97 if i read the question correctly
Maria _ I got that to!
love your math
97 is the right answer!
97 is the right answer
The answer can be 96, 97,98 and 99
97 was my first answer as well.
Why is the answer 97 and not 95,96,98 or 99? I have to explain this to a 3 year old, please help.
To determine which number will have the same result when rounded to the nearest ten or hundred, we need to understand rounding rules.
To round to the nearest ten:
- Look at the units digit.
- If the units digit is 0 to 4, keep the tens digit and replace all digits after the tens digit with zeros.
- If the units digit is 5 to 9, add 1 to the tens digit and replace all digits after the tens digit with zeros.
To round to the nearest hundred:
- Look at the units and tens digits.
- If the units and tens digits are 00 to 49, keep the hundreds digit and replace all digits after the hundreds digit with zeros.
- If the units and tens digits are 50 to 99, add 1 to the hundreds digit and replace all digits after the hundreds digit with zeros.
Let's apply these rounding rules to each number:
1. For 97:
- Rounding to the nearest ten: The units digit is 7, which is closer to 10 than 0, so we add 1 to the tens digit and replace the units digit with zero. The number rounds to 100.
- Rounding to the nearest hundred: The units and tens digits are 97, which is closer to 100 than 0, so we add 1 to the hundreds digit and replace the tens and units digits with zeros. The number rounds to 100.
2. For 118:
- Rounding to the nearest ten: The units digit is 8, which is closer to 10 than 0, so we add 1 to the tens digit and replace the units digit with zero. The number rounds to 120.
- Rounding to the nearest hundred: The units and tens digits are 18, which is closer to 0 than 100, so we keep the hundreds digit and replace the tens and units digits with zeros. The number rounds to 100.
3. For 5,179:
- Rounding to the nearest ten: The units digit is 9, which is closer to 10 than 0, so we add 1 to the tens digit and replace the units digit with zero. The number rounds to 5,180.
- Rounding to the nearest hundred: The units and tens digits are 79, which is closer to 100 than 0, so we add 1 to the hundreds digit and replace the tens and units digits with zeros. The number rounds to 5,200.
4. For 5,091:
- Rounding to the nearest ten: The units digit is 1, which is closer to 0 than 10, so we keep the tens digit and replace the units digit with zero. The number rounds to 5,090.
- Rounding to the nearest hundred: The units and tens digits are 91, which is closer to 100 than 0, so we add 1 to the hundreds digit and replace the tens and units digits with zeros. The number rounds to 5,100.
So, the numbers 97 and 118 have the same result when rounded to the nearest ten or hundred, which is 100.
