as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below. fraction and use a forward slash to input fractions i.e., 12/3 . An example of a negative mixed fraction: -5 1/2. There have been a number of different standards for the inch in the past, with the current definition being based on the international yard. One of the earliest definitions of the inch was based on barleycorns, where an inch was equal to the length of three grains of dry, round barley placed end-to-end. Another version of the inch is also believed to have been derived from the width of a human thumb, where the length was obtained from averaging the width of three thumbs: a small, a medium, and a large one.

Current use: The centimeter, like the meter, is used in all sorts of applications worldwide (in countries that have undergone metrication) in instances where a smaller denomination of the meter is required. Height is commonly measured in centimeters outside of countries like the United States. Someone ate 1/10 of a cake, leaving only 9/10. If you eat 2/3 of the cake left, how much of a whole cake will you have eaten? Generally available in 7.500 to 7.650 Metre lengths in Grade 43; however other lengths and grades are available. For your information Kg/m refers to the Kilograms per Metre of the section, as an example a 4.200 Metre length of 40 x 40 x 3mm (SHS) Square Steel Hollow Section (3.45 Kg/m) would weigh (4.2 x 3.45) 14.49 Kg’s Total.

the decimal would then be 0.05, and so on. Beyond this, converting fractions into decimals requires the operation of long division. The gauge (imperial) is half the imperial diameter (in 16th of an inch) of the screw head, roughly. The precise relationship of imperial screw head sizes and the gauge can be calculated. The formula is as follows: Slotted screws are fast becoming history and cross head screws are now the fashion but it must be remembered that a cross head screw can either be a Philips screw (top image below)or a pozidrive/supadrive screw (bottom image below). They both require a different type of driver which can be found below. Fraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to the addition section as well as the equations below for clarification. a

Don’t worry if you don’t follow this as not many people know about these relationships, let alone use them. More about Screws Although technically you can use a Phillips driver on a Pozidrive screw and vice versa, their not really designed to fit and under torque load (when you are screwing the screw in) in pretty much all situations it will slip and damage the head of the screw making it difficult to either screw in the screw or remove it, so it’s always best to use the right tool for the job. ST – Self Tapping; These screws have a tip that will allow them to be screwed into (typically wood) without a pilot hole being drilled. This saves a lot of time!

Definition: A centimeter (symbol: cm) is a unit of length in the International System of Units (SI), the current form of the metric system. It is defined as 1/100 meters. There are 420 pupils in the school. Two hundred fifty-two pupils go to the 1st level. Write as a fraction what part of the pupils goes to the 1st grade and what part to the 2nd grade. Shorten both fractions to their basic form. the numerator is 3, and the denominator is 8. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 Definition: An inch (symbol: in) is a unit of length in the imperial and US customary systems of measurement. An inch was defined to be equivalent to exactly 25.4 millimeters in 1959. There are 12 inches in a foot and 36 inches in a yard.
