Count in tens. What are the two tens either side of 509?
500 is smaller and 510 is bigger.
Any ten smaller than 500 is going to be further away than 500
Any ten bigger than 510 is going to be further away than 510
So the answer is going to be one of 500 and 510.
Now,
how far is 500? 509 - 500 = 9 units
how far is 510? 510 - 509 = 1 unit
So which is the smaller distance? 1 unit to 510. So 510 is the nearest 10.
645 rounded to the nearest ten would simply be 650.
459 to the nearest ten thousand? (not thousandth?) 459 would round down to 0..
The number is already rounded to the nearest ten.
672 rounded to the nearest ten would be equal to 670.
It depends. If it rounds to the nearest ten, which you're probably asking, it would round to 70. to the nearest hundred, it would be 100. To anything greater than that it would round to zero, and anything less than the nearest ten, it would round to 74.
To round 95 to the nearest ten, you would round it down to 90.
It would be 160 rounded to the nearest ten
645 rounded to the nearest ten would simply be 650.
To the nearest ten - it would be 7900
To the nearest ten cents it will round up to give 67.20 as your answer. It would round down to 67 for the nearest dollar.
Rounding 13 to the nearest ten would be 10
459 to the nearest ten thousand? (not thousandth?) 459 would round down to 0..
The number is already rounded to the nearest ten.
672 rounded to the nearest ten would be equal to 670.
The answer would be 150 if you were to round 148 to the nearest ten.
101469 rounded to the nearest ten would be 101470.
0.32276 to the nearest ten thousandth would be 0.3228.
