Question

How do you round to the nearest unit?

Help me here plz thanks​

Answer 1

Bonjour Cocinelle

Explanation:

Rounding to the nearest unit means to find the nearest integer to a given number.

Basically, you have to get rid of the decimal part, if any.

As an immediate corollary, you have that if a number x

is already an integer, then there's no point in rounding it, since the result would be x itself.

Now, let's assume that our number actually has a decimal part, for example

4.687

It might help you to think of this number as

4+0.687

to clearly see that 4.687 lies between

4 and 5

, since it is something (0.687) more than 4 , but still not 5

So, the question is: is our number closer to

4 or to 5? Which, in turn, means to ask: the decimal part that we've added,

0.687 , is nearest to 0 or 1 ?

If it is nearest to 0 , it means that our number is more than 4 , but still nearer to

4

than it is to 5, otherwise it is "far enough" from 4 to be nearer to 5

Since halfway between 0 and 1 is 0.5 , and our decimal part is 0.687>0.5 , we can say that 4.687 is rounded to

5.

Are you too miraculer me too

Answer 2

Rounding to the nearest unit means to find the nearest integer to a given number. Before you remove the decimal take the first number of the decimal (45.68) Take 6 (The number that comes first after the decimal).

If the number is 5 and less then convert the number to a lower number.

If the number is more than 5 then convert the number to a higher number.

Ex: 34.41. The answer would be 33 because 4 is less than 5.

Ex: 34.61. The answer would be 35 because 6 is more than 5.

I hope this helps :)
