About Decimals Formula
The decimals formula is helpful when working with decimals and performing fundamental arithmetic operations. An integral whole number with a decimal or fractional component makes up a decimal number.
What are the Decimals Formulas?
The four decimals formulas described here can be used to manipulate decimals and execute a variety of operations on them. Furthermore, we can understand the change in decimal place value across each operation with the help of these formulas.
Decimals Formula??????? Formula 1
A fraction having a denominator of ten or a multiple of ten can be simply stated as a decimal. The number of decimal places in the result is equal to the number of zeros in the multiple of 10 in the denominator when using the decimal formula.
a/10 = 0.a
a/100 = 0.0a
a/1000 = 0.00a
Decimals Formula??????? Formula 2
By multiplying a decimal by 10 or a greater power of 10, which is equal to the number of decimal digits, a decimal can be transformed to a whole number.
0.a × 10 = a
0.0a × 100 = a
0.00a × 1000 = a
Decimals Formula??????? Formula 3
The number of digits (in each of the numbers) after the decimal point is added in decimal multiplication, and the resultant product has the same number of digits after the decimal point.
0.00a × 0.0b = 0.0000c
Decimals Formula??????? Formula 4
The difference of decimals in each of the numbers is taken in the decimal division, and this number of decimals is reported in the resultant answer.
0.000a/0.0b = 0.0c
