Tips for Decimal

1. Decimals are a method of writing fractional numbers without writing a fraction having a numerator and denominator.

The fraction 7/10 could be written as the decimal 0.7. The period or decimal point indicates that this is a decimal. The decimal 0.7 could be pronounced as SEVEN TENTHS or as ZERO POINT SEVEN. If a decimal is less than 1, place a zero before the decimal point. Write 0.7 not .7

Hundredths have two digits after the decimal point. The decimal 0.36 is pronounced "thirty-six hundredths" or "zero point thirty-six". It is equal to the fraction 36/100.

Thousandths follow a similar pattern. They have three digits after the decimal point. The decimal 0.749 is pronounced "seven hundred forty-nine thousandths" or "zero point seven forty-nine".

2. Adding Decimals is just like adding other numbers. Always line up the decimal points when adding decimals. Remember to put the decimal point in the proper place in your answer.

3. Subtracting Decimals is just like subtracting other numbers. Always line up the decimal points when subtracting decimals. Remember to put the decimal point in the proper place in your answer.

4. How to divide a four digit decimal number by a two digit number (e.g. 0.4138 ?17).

Place the divisor (17) before the division bracket and place the dividend (0.4138) under it.

    ______      
 17)0.4138

0.0243 remainder 7
