Question

The opposite number of 25 is

Answer 1

As per the data given in the question,

We have to determine the opposite number of 25.

As we know that,

On a number line we generally divides all the number from the Left of zero and from the right of zero.

As we know that,

There are total of 3 types of number-

Positive number which is normally on the right of zero

Negative number which are normally placed in the left of zero.

and third one is zero, which is placed at centered.

So, technically if we assume have we have Rs 5 as surplus and then in that case the opposite of Rs 5 surplus will be deficit of Rs 5 which will be mathematically denoted as minus of Rs 5

So, we can say that,

-25 will be opposite of 25.

Answer 2

As per the data given in the question,

In the above question, it is given that,

The given number is $=25$

We have to find the opposite number of $25$ .

Here we have to use the number line to find the opposite numbers,

As we know in the number line we have zero as a centre and one side is a positive value while another side is a negative value.

While the opposite of a number is considered to be the same distance from zero but in opposite direction.

Hence the opposite of 25 is -25.

An Example of a number line of the opposite of 5 is -5. as shown in the figure.
