It depends on what you are rounding to. If you are rounding to the nearest 10, you look at the value in the ones place. If it is 0 to 4, then it is rounded down. If it is 5 to 9, we round up. In this case we round down, so it becomes 750. If rounding to the nearest hundred, then the digit is the tens place is to one to look at. As it is a 5, we round up, giving us 800.
To round any number to hundreds place, look at the number in the tens place. If the number is less than 5, leave the number in the hundreds place as it is. If the number in tens place is 5 or above, round the number in the hundreds place up one. For the number 98143, the number in tens place is four, so it would be rounded to 98100.
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the nearest tens and the nearest ones respectively. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
