What is Decimal(Definition, Example, Conversion)

In mathematics calculation may be you heard about lots of number system like whole number, natural number, even number, odd number, rotational numbered etc.so in mathematics on of number which is called decimal number and here we will discuss about more details on it.

We can define decimal according to its nature that’s containing whole number part and fraction part is separated by decimal point.in decimal number that dot is consider as decimal point.in decimal point all digit have unique place number.

Learn What is Decimal With Example

let’s assume we have number which is 75.5 So here as you can 75 is whole Number and after decimal point 5 is called fraction part. that (.) called is decimal point in between of 75.5

Ok here is Another one example with figure as you can see value is 12.5 in which 5 is place of tenths place.

what is decimal number

So here 1 is tens place, 2 is on ones place and after decimal point 5 is on tenths places

Decimal Representations

in decimal number all number have unique place and representations of that number so here we take example of 12.5

12.5=125/10

So if we are looking of place of that number so here we can found that

1 representations the power 101 that is tens position.

2 representations the power 100 that is tens position.

5representations the power 10-1 that is tens position.

So as you can see how digit is work According to power of 10 in decimal number

What is place value in decimal number

decimal place value

place value in decimal number is very crucial because converting any decimal number to fraction form its required to know that after decimal point which digit on place .So our taken value is here 0.123 as you can see we are moving towards left side so all digit after decimal point has unique place value.

so as you can see that 1 digit is on tenth places means that it is on 1/10. so as you can see that 2 digit is on hundred place means that is on 2/100. so as you can see that 3 digit is on thousand place means that is on 3/1000.

so if we want to convert that number in decimal to fraction form so we can write like 0.123=123/1000.

Decimal to fraction conversion

so if you are looking to convert decimal to fraction of any number you must aware about decimal place value.so here we have some example for you

0.8 is decimal number and we are looking to convert in fraction form so how we can do?

0.8=8/10 (8 is place of tenths) 4/5(this is final Answer )

0.6 is decimal number and we are looking to convert in fraction form so how we can do?

0.6=6/10 (6 is place of tenths) 3/5(this is final Answer )

here as you can see how we are done with simple step within some times.
