###### Steps for Decimals Operation

Adding Decimals:

Align the decimal points of the two numbers.

Add the digits in each place value column.

If the sum of any column is 10 or more, carry over the extra digit to the next column.

Write the final sum with the decimal point in the same place as the original numbers.

###### Subtracting Decimals:

Align the decimal points of the two numbers.

Subtract the digits in each place value column.

If the digit in the minuend column is smaller than the digit in the corresponding subtrahend column, borrow from the next column to the left.

Write the final difference with the decimal point in the same place as the original numbers.

###### Multiplying Decimals:

Ignore the decimal points of the two numbers and multiply as if they were whole numbers.

Count the total number of digits to the right of the decimal point in the original numbers.

Place the decimal point in the product so that there are the same number of digits to the right of the decimal point as there were in the original numbers.

###### Dividing Decimals:

Move the decimal point in the divisor (the number being divided into the dividend) to the right until it becomes a whole number.

Move the decimal point in the dividend (the number being divided) to the right the same number of times as the divisor.

Divide the two numbers as we would with whole numbers.

Place the decimal point in the quotient directly above the decimal point in the dividend.

Fractions (adding, subtracting, multiplying, and dividing)

Fractions are a way of representing a part of a whole. They consist of two numbers, the numerator (top number) and the denominator (bottom number), separated by a horizontal line.
