Rounding and Estimating Numbers

When rounding to a specific place, take a look at the digit immediately to the right of the target, in this case, the tenths place. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.

0.08709 rounded to the nearest hundredths place becomes 0.09

1000

400

200 is divisible by 100, so it doesn't need to be rounded.

502.4

Well, isn't that just a happy little number we have here? When we round 4.895 to the hundredths place, it becomes 4.90. Remember, we look at the digit right after the hundredths place to decide whether to keep the same number or round up. Just like adding a touch of paint to bring out the beauty in a landscape, rounding helps us simplify numbers and make them easier to work with.

861 rounded to the nearest 100 is 900

To round 2.51 to the nearest whole number, you look at the digit immediately to the right of the decimal point, which is 5 in this case. Since 5 is equal to or greater than 5, you round the number up. Therefore, 2.51 rounded to the nearest whole number is 3.

45.678 rounds to 46.

1400

1350 ? Look at the 'tens' number, '5' in this case. If '5' or greaterm then add '1' to the 'hundreds' number.

1349 is nearer 1300

but

1350 is nearer 1400

NB THis applies to any numbers. Given a million, you inspect the 'hundred thousand' number. or 'tens' inspect the 'units' number.

Oh, dude, rounding 2439 to the nearest hundred is like choosing the closest big brother for it to hang out with. So, 2439 is closer to 2400 than 2500, right? That means 2439 rounded to the nearest hundred is 2400. Easy peasy, lemon squeezy!

23.4

Oh, dude, you want me to do math now? Fine, fine. So, 5.275 rounded to 1 decimal place is 5.3. Like, it's not rocket science, but yeah, there you go.

To round 248.99 to the nearest tenth, we look at the digit in the hundredth place, which is 9. Since 9 is greater than or equal to 5, we round up the digit in the tenths place by 1. Therefore, 248.99 rounded to the nearest tenth is 249.0.

1100

To round 634 to the nearest hundred, we look at the digit in the tens place, which is 3. Since 3 is less than 5, we keep the hundreds place digit the same (6) and change all digits to the right to zero. Therefore, rounding 634 to the nearest hundred gives us 600.

Well, let's take a moment to appreciate the beauty of numbers. If we look at 1017.36 with care and precision, we can see that when rounded to the nearest hundredth, it becomes 1017.36. Just a gentle adjustment to keep things neat and tidy.

156 rounded to the nearest hundreds place is 200.

Well, isn't that a happy little number! When we round 5.97 to one decimal place, it becomes 6.0. Just a little adjustment to make it even more delightful.
