## Decimals

Decimals Decimals are the foundations of math as we know it, without this key aspect; nothing would be as precise, the currency system would fall on its knees, and the chance of dying will be higher since the doctors won't know the exact amount of medicine to give you. SO lets lets start the escapade on the ominous. decimals What is decimals The decimal numeral system is the standard system for denoting non integer numbers, for example: 9.75 is a decimal because it represents a non integer number. Another way to think about decimals are that they are corresponding with fractions, for example 4/10 is the same as 0.4. Fraction to Decimals Fractions, Decimals, Percentages and Money Equivalents (E and p) Fractions, Decimals, Percentages and Money Equivalents (£ and p) Fractions and decimals are similar because they both are ways to express partial numbers. Additionally, fractions can be expressed as decimals by performing the division of the ratio. (For example, 3/4 is 0.25 - 25% -0z - 20% - - equivalent to 3 divided by 4, or 0.75.) when do we use decimals We use decimals everyday while dealing with money, weight, length etc. Decimal numbers are used in situations where more precision is required than the whole numbers can provide. For example, when we calculate our weight on the weighing machine, we do not always find the weight equal to a whole number on the scale. multiplying Ignore the decimal points and multiply as usual... Count how many total digits are on the right side of the decimal points in the values you are multiplying... Place the decimal point in your answer so there are this many digits to the right. For example: 4.621 x 5.634 count up all the decimal positions, in this case it is 6. now forget the decimals (4621 x 5634) once you get your answer (26,034,714.), go to the sixth digit and place your decimal (26.034714) Division To divide decimals the easiest way; you have to get rid of them. Start of by by moving your decimals point to the right until you get a whole number, you need to do this with both the dividend and the divisor, remember is you move the decimal point 2 places to the right for the divisor, you need to do the same for the dividend. For example: 0.56/7.6= 56/760. This will help you loads, since you wont have to worry about the decimal anymore.( 0.56 / 7.6 = 0.07368421) = (56 / 760 = 0.07368421) standard form Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 x 103 = 4000. So 4000 can be written as 4 x 103. This idea can be used to write even larger numbers down easily in standard form. 3.1 2.65 0.7 2.2 5.6 1.24 8.2 0.1 0.12 7.7 0.3 powered by P PIKTOCHART
