What is called decimals? The numbers bac called are those decimals numbers smaller than a full. It is the number on the right side of the decimal point or period bac or periods. The numbers are decimals fractions with denominator a power of ten (10, 100, 1000, 10,000. Etc) Examples of decimals: 1) 0.003 2) 0.50 3) 0.123 4) 23.02 5) 1.52335 A. ADDITION decimal bac NUMBERS
(Image bac from http://www.coolmath.com) It's easy to ADD as a decimal numbers. Just remember to pagtapat-tapatin the decimal point (or period) and then can be the add-in. For example: ADD 2.02 + 0.003 + 4.125 = 21.0021 + 0.003 2.02 4.125 27.1501 21.0021 B. subtraction of decimals NUMBERS
(Image bac from http://www.enchantedlearning.com) As addition, you should just confess before the decimal point subtract bac the smaller number to the larger number. Examples: subtraction 205.0023 to 17.05 7.051 205.0023 197.9513 C. multiplication of decimals NUMBERS
In pagmumultiply decimals, remember to count the number of seats to the right of the decimal point or the so-called decimal places. Example: How many decimal places the number 23.0012? From the decimal point, with four decimal places this number. Several decimal places and nunerong bac 9.023? It has three decimal places. Multiply 23.0012 by 9.023. 1) Just do the standard multiplication procedure ==> 2075398276 Where to place the decimal point? Please ADD the number of decimal bac places of 23.0012 (4 or four) and number of decimal places of 9.023 (3 or three) The total number of decimal places as 2 numbers multiplied is 4 + 3 = 7 7 Given the number of decimal places, from the right, count 7 left and there put the decimal point. So 2075398276 would be 207.5398276 D. DIVISION of decimals
Example: bac DIVIDE by 4.1 23.5 1) If DIVISOR (the number going to divide) is not the whole number (whole number), move the decimal bac point to be a whole number it. In our example, the DIVISOR is 4.1 because it is not a whole number, we move the decimal point to be a whole number it. 4.1 ==> 41 2) Move the decimal point also the dividends of the same as moving the decimal point DIVISOR. Given a decimal placee we just moved the decimal point of 4.1, a decimal place we also moved the decimal point of the dividend. 23.05 ==> 230.5 3) dividing bac the habit. 230.5 divided by 41 = 5.62195122 (the length of decimal places based on how many asking the question) 4) To make sure the answer is correct, then multiply the quotient in DIVISOR. Once you've got the dividend, the right answer. 5.62195122 x 41 = 230.5
