Teach Your Children Arithmetic Fractions Los Diablos Fractions. Ugh! I could hear the cries of my students at any time enter into the realm of these nasty little devils. At any moment we are engaged in a field of mathematics that require heavy amounts of work, students who act as if they were entering Hades after an arduous crossing of the river Acheron, led by fearless l'uomo Charon ferries and dog Three-headed Cerberus. Ouch! It was that bad. However, in all reality, we call bugbears these fractions are not as demonic as they are to be made. And when you consider how important it is that the study of all areas of mathematics, giving them the best - and respect. In the early centuries, the children encounter more of those entities that are inherently difficult to count. Unlike numbers, which consist of a hand, the fractions (or rational, as they are called) consist of two parts: the numerator, or faster, and the denominator, or bottom. Almost everyone knows that. And these monsters are quite favorable to perform the arithmetic operations of multiplication or division (which is not discussed here, just waiting to write the article). However, adding or subtracting - now we are talking seriously. Crisis students the idea of adding two fractions with different denominators exceptional, to say nothing of three fractions with different funds. I suppose that "the money" does not apply here. In any case, even the addition of fractions is not difficult. We only need a common field of play and that I am referring to the common denominator. In particular, we want the lowest common denominator, or LCD, for short. Once we have the LCD display, make a rapid conversion of the numerators and then add together. Case closed. But to achieve this LCD is what gives students the most problems. Now I could go in the method of the LCD display, first the decomposition in each of the first funds - a process known as decomposition in first - and then get the screen as taking all the various cousins and cousins is common to most power - ugh, I always confused by all this Mumbo Jumbo. Hey wait, there's an easier way? Yes, fortunately there. Since most students lea to obtain a common denominator (not necessarily the LCD screen, though) by multiplying the two funds together, there will be our basic approach to this procedure. The only problem with this method is that it may need to multiply two numbers. In general, I mean, maybe 12 or 18 x 24 x 16. Most students have a computer so use that is not really a problem. (Although, if you lea my techniques, which do not have the calculator.) Well, we come to the meat of this method. Let us take a concrete example. Suppose that you need to add 5 / 18 and 5 / 12 together. First, we need to have the LCD display of 12 and 18. Before you multiply these numbers together, we must note that the greatest common factor of 12 and 18 is 6. The highest common factor or GCF of two numbers, which is more equally the two numbers. For the LCD display, all you have to do is to multiply together two numbers, 12 x 18 = 216, then dividing the result by the GCF of 6, for 216 / 6 = 36. Soon! LCD 12 and 18 is 36. N Main decompositions, skipping several cousins, do not worry about the higher power. Finally, add the two fractions, multiply the numerator by the factor appropriate to the settings section. For example, since 36/18 = 2, we multiply 5 5 / 18 from 2 to 5 / 18 = 10/36; similarly, since 36/12 = 3, multiply 5 by 3 to get 15 and 5 / 12 = 15 / 36. Finally, 5 / 18 + 5 / 12 = 10/36 + 15/36 = 25/36. Try this method for its size, and I am sure that you do not take any boat trips or any time soon Cerberus Charon. Until next time ...
