DECIMALS

WHAT ARE DECIMALS

• a fraction whose denominator is a power of ten and whose numerator is expressed by figures placed to the right of a decimal point. the system of decimal numerical notation.

HOW TO ADD DECIMALS

• Write down the numbers, one under the other, with the decimal points lined up
• Put in zeros so the numbers have the same length (see below for why that is OK)
• Then add using column addition, remembering to put the decimal point in the answer

HOW TO SUBTRACT DECIMALS

• Write down the two numbers, one under the other, with the decimal points lined up.
• Add zeros so the numbers have the same length
• Then subtract normally, remembering to put the decimal point in the answer

HOW TO DIVIDE DECIMALS

• If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.
• Divide as usual. ... Put decimal point directly above decimal point in the dividend.

HOW TO MUTIPLY DECIMALS

• Multiply normally, ignoring the decimal points.
• Then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined
