So -7 is absolutely\nexpressed in form of a rational number.\nNow, in this we are going to learn about operations with integers and rational\nnumbers. All mathematical operations namely addition, subtraction,\nmultiplication and division can take place with both integers and rational\nnumbers.\nAs integers all the properties of addition namely closure, commutative,\nassociative satisfy with rational numbers too.\nThere exist an additive identity 0 (zero), such that we add 0 to any rational\nKnow More About Is -25 an Irrational Number\nnumber, the rational number remains unchanged. Similarly, there exists an\nadditive inverse for every rational number such that the sum of the number and\nits additive inverse is zero.\nIn the same way, all subtraction properties of integers satisfy with rational\nnumbers.\nTo divide one rational number by another, we will convert the dividend to its\nreciprocal and then the sum of division converts to the simple sum of\nmultiplication, which can be solved easily.\nWhen we find the sum or the difference of any two rational numbers, we need to\nfirst find the LCM of the denominators. On finding the LCM of denominators, we\nchange the rational number to its equivalent rational number such that the\ndenominator becomes equal to the LCM.\nFinally addition or subtraction of the numerator can be done. Moreover to find\nthe product of two rational numbers is very easy. To look into it, we simply need\nto multiply the numerator with the numerator and the denominator with the\ndenominator.\nOn getting the new rational number as the product, we convert it to the standard\nform.\n\";s:5:\"thumb\";s:63:\"images/t/1784/operations-with-integers-and-rational-numbers.jpg\";s:6:\"thumb2\";s:64:\"images/t2/1784/operations-with-integers-and-rational-numbers.jpg\";s:9:\"permalink\";s:45:\"operations-with-integers-and-rational-numbers\";s:5:\"pages\";s:1:\"3\";s:6:\"rating\";s:1:\"0\";s:5:\"voter\";s:1:\"0\";}i:4;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"462491\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:7:\"zeenbee\";s:9:\"author_id\";s:6:\"585227\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:26:\"101 Easy Science Projects.\";s:11:\"description\";s:26:\"101 Easy Science Projects.\";s:5:\"thumb\";s:43:\"images/t/4625/101-easy-science-projects.jpg\";s:6:\"thumb2\";s:44:\"images/t2/4625/101-easy-science-projects.jpg\";s:9:\"permalink\";s:25:\"101-easy-science-projects\";s:5:\"pages\";s:1:\"2\";s:6:\"rating\";s:1:\"5\";s:5:\"voter\";s:1:\"1\";}i:5;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"499785\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:10:\"testbankby\";s:9:\"author_id\";s:6:\"610169\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:91:\"Testbank For Child Health Nursing Partnering with Children and Families 2nd Edition by Ball\";s:11:\"description\";s:91:\"Testbank For Child Health Nursing Partnering with Children and Families 2nd Edition by Ball\";s:5:\"thumb\";s:96:\"images/t/4998/child-health-nursing-partnering-with-children-and-families-2nd-edition-by-ball.jpg\";s:6:\"thumb2\";s:97:\"images/t2/4998/child-health-nursing-partnering-with-children-and-families-2nd-edition-by-ball.jpg\";s:9:\"permalink\";s:78:\"child-health-nursing-partnering-with-children-and-families-2nd-edition-by-ball\";s:5:\"pages\";s:1:\"2\";s:6:\"rating\";s:1:\"0\";s:5:\"voter\";s:1:\"0\";}i:6;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"552891\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:11:\"bank3rdtest\";s:9:\"author_id\";s:6:\"622195\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:89:\"Testbank For Organizational Behavior Science The Real World and You 8th Edition by Nelson\";s:11:\"description\";s:89:\"Testbank For Organizational Behavior Science The Real World and You 8th Edition by Nelson\";s:5:\"thumb\";s:94:\"images/t/5529/organizational-behavior-science-the-real-world-and-you-8th-edition-by-nelson.jpg\";s:6:\"thumb2\";s:95:\"images/t2/5529/organizational-behavior-science-the-real-world-and-you-8th-edition-by-nelson.jpg\";s:9:\"permalink\";s:76:\"organizational-behavior-science-the-real-world-and-you-8th-edition-by-nelson\";s:5:\"pages\";s:1:\"2\";s:6:\"rating\";s:1:\"0\";s:5:\"voter\";s:1:\"0\";}i:7;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"148427\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:7:\"Printer\";s:9:\"author_id\";s:1:\"0\";s:14:\"author_website\";s:27:\"http://www.upstream.com.au/\";s:5:\"title\";s:53:\"5 TIPS ON HOW TO SAVE MONEY WITH PRINTERS AND COPIERS\";s:11:\"description\";s:133:\"If you have a printer or copier you\'ll know what the expenses are, but you might need help to work out how to streamline your costs.\n\";s:5:\"thumb\";s:71:\"images/t/1485/5-tips-on-how-to-save-money-with-printers-and-copiers.jpg\";s:6:\"thumb2\";s:72:\"images/t2/1485/5-tips-on-how-to-save-money-with-printers-and-copiers.jpg\";s:9:\"permalink\";s:53:\"5-tips-on-how-to-save-money-with-printers-and-copiers\";s:5:\"pages\";s:1:\"1\";s:6:\"rating\";s:1:\"0\";s:5:\"voter\";s:1:\"0\";}i:8;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"186332\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:14:\"donna59walters\";s:9:\"author_id\";s:5:\"57469\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:80:\"Broan 100HFL Directionally-Adjustable Bath Fan With Heater And Fluorescent Light\";s:11:\"description\";s:23:\" 2.0 out of 5 \n \";s:5:\"thumb\";s:98:\"images/t/1864/broan-100hfl-directionally-adjustable-bath-fan-with-heater-and-fluorescent-light.jpg\";s:6:\"thumb2\";s:99:\"images/t2/1864/broan-100hfl-directionally-adjustable-bath-fan-with-heater-and-fluorescent-light.jpg\";s:9:\"permalink\";s:80:\"broan-100hfl-directionally-adjustable-bath-fan-with-heater-and-fluorescent-light\";s:5:\"pages\";s:1:\"1\";s:6:\"rating\";s:1:\"0\";s:5:\"voter\";s:1:\"0\";}i:9;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"478886\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:13:\"mobstyleindia\";s:9:\"author_id\";s:6:\"579118\";s:14:\"author_website\";s:23:\"http://www.mobstyle.in/\";s:5:\"title\";s:55:\"Red -
