Decimals are numbers that include a whole and a fractional part, representing values for quantities that are whole plus a part of a whole.

The dot present between the whole number is called the decimal point.

Explanation: In this image, 321.18. Here, we take 321.18 as a decimal number, consisting of 321 and 18 separated by a point called a decimal point.

When subtracting decimals, position of their decimal points and subtract each corresponding digit to find the difference between two decimal numbers.

Explanation: In this image, we are subtracting 321.09 from 987.65 to get the result 666.56.

We write decimal numbers as fractions where the decimal is the numerator and the place value is the denominator.

Explanation: In this image, we take 0.6, as a decimal number. The six is in the tenth place, so we place 6 over 10 to create the fraction, \$6/10\$.

A fraction is a representation of a number that is expressed as a numerator over a denominator.

Explanation: In this image, we convert the fraction 74/100 to a decimal number by taking its fractional part. We obtain 0.74 as the decimal number, where the numerator is 74 and the denominator is 100.
