Question

Decimal form of $\dfrac{{48}}{{100}}$ is :

Answer 1

Hint: In order to determine the decimal form of the above question , already written in the form of rational number ( the number which can be expressed as in the form of $\dfrac{p}{q}$ , where p is numerator and q is denominator also q$ \ne $0.). The first place after the decimal that is to the right of the decimal is called the tenth place and the number placed just after and to the right of the decimal is known as the number of tenths. Similarly , The second place after the decimal that is to the right of the decimal is called the hundredth place and the number placed just after the tenth place is known as the number of hundredths.

Complete step-by-step solution:
We know that a decimal number contains a whole number and a fractional portion which is separated by a point called decimal. There are certain places depending upon the position of a digit in a number that has got some certain value which is called as its place value. These place values are named as tenths , hundredths , thousandths.

We can represent the number as a decimal number by making their denominator tenth ( $\dfrac{1}{{10}}$ ) , hundredth ( $\dfrac{1}{{100}}$) , thousandth ( $\dfrac{1}{{1000}}$).
Here , the number given $\dfrac{{48}}{{100}}$ is itself having the denominator as $\dfrac{1}{{100}}$ that is having hundredth , we just need to write the number and put the symbol at the correct spot that is the decimal point should be 2 places from the right because 100 has two zeroes and so the last digit of the number should be at the hundredth place value that is $0.48$.
$\dfrac{{48}}{{100}}$=$0.48$.


Additional Information :
And the multiplication of a decimal by tens , hundreds and thousands or etc. itself means that the decimal will be moved to the right side by as many as the number of zeroes are there in the multiplier.. If the decimal is being moved to the right, the exponent will be negative which automatically means that the number will be divided and placed in the denominator. Try to cancel out factors from numerator and denominator , you will get your required result.

Note: Do not Forget to verify the end of the result with the zeroes.
-If you multiply a decimal with 10 , then the decimal point will be moved to the right side by 1 place.
-If you multiply a decimal with 100 , then the decimal point will be moved to the right side by 2 place.
-Also remember that any number for example – 150 is a number can also be expressed as 150.0 in the form of decimal.
