Fractions of Class 5/ Unit-7

#BrainWa A fraction (from Latin fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction (examples: {\displaystyle {\tfrac {1}{2}}}{\tfrac {1}{2}} and {\displaystyle {\tfrac {17}{3}}}{\displaystyle {\tfrac {17}{3}}}) consists of a numerator displayed above a line (or before a slash), and a non-zero denominator, displayed below (or after) that line. Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals. #Asansol_City #HindMotor_City #Barakar_City #Uttarpara_City #Kulti_City #Bally_City #Neyamatpur_City #Belur_City #Kumarpur_City #Liluah_City #Gopalpur_City #HowrahJunction_City #ChelidanGal #AsansolJunction_City #AsansolRailpar #Chittaranjan_City #AsansolDhadka #MadhupurJunction_City #Andal_City #JasidihJunction_City #Raniganj_City #Jhajha_City #Jamuria_City #Jamui_City #Ukhara_City #KiulJunction_City #Durgapur_City #HathidahJunction_City #Benachatti_City #MokamehJunction_City #BidhanNagar_City #Barh_City #PaschimBardhaman_District #BakhtiyarpurJunction_City #Bardhaman_City #Fatwa_City #Saktigarh_City #PatnaSaheb_City #Palsit_City #RajenderNagarBihar_City #Rasulpur_City #PatnaJunction_City #Memari_City #Debipur_City #Pundooah_City #Magra_City #BandelJunction_City #Hooghly_City #Chuchura_City #ChandanNagar_City #Mankundu_City #Bhadreshwar_City #Baidyabati_City #SeoraphuliJunction_City #Serampore_City #Rishra_City #Konnagar_City In positive common fractions, the numerator and denominator are natural numbers. A common fraction is a numeral which represents a rational number. That same number can also be represented as a decimal, a percent, or with a negative exponent. For example, 0.01, 1%, and 10−2 all equal the fraction 1/100. An integer such as the number 7 can be thought of as having an implicit denominator of one: 7 equals Other uses for fractions are to represent ratios and division.[1] Thus the fraction is also used to represent the ratio 3:4 (the ratio of the part to the whole) and the division 3 ÷ 4 (three divided by four). The non-zero denominator in the case using a fraction to represent division is an example of the rule that division by zero is undefined. We can also write negative fractions, which represent the opposite of a positive fraction. For example, if represents a half dollar profit, then − represents a half dollar loss. Because of the rules of division of signed numbers, which require that, for example, negative divided by positive is negative, , all represent the same fraction, negative one-half. Because a negative divided by a negative produces a positive, represents positive one-half. In mathematics the set of all numbers that can be expressed in the form a/b, where a and b are integers and b is not zero, is called the set of rational numbers and is represented by the symbol Q, which stands for quotient. The test for a number being a rational number is that it can be written in that form (i.e., as a common fraction). However, the word fraction is also used to describe mathematical expressions that are not rational numbers, for example algebraic fractions (quotients of algebraic expressions), and expressions that contain irrational numbers, such as √2/2 (see square root of 2) and π/4 (see proof that π is irrational).
