Question 2. \nIf the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through examples. \nAnswer: \nYes, if we multiply any number with zero the resultant product will be zero. \nExample: 2 \u00d7 0 = 0, 5 \u00d7 0 = 0, 9 \u00d7 0 = 0 If both numbers are zero, then the result also be zero. \n0 \u00d7 0 = 0 \nYes, if the product of two whole numbers is zero, then both of them will be zero.<\/p>\n
Question 3. \nIf the product of two whole numbers is 1, can we say that one of both of them will be 1? Justify through examples. \nAnswer: \nIf only one number be 1 then the product cannot be 1. \nExamples: 5 \u00d7 1 = 5, 4 \u00d7 1 = 4, 8 \u00d7 1 = 8 \nIf both number are 1, then the product is 1. \n1 \u00d7 1 = 1<\/p>\n
Question 4. \nFind using distributive property: \n(a) 728 \u00d7 101 \n(b) 5437 \u00d7 1001 \n(c) 824 \u00d7 25 \n(d) 4275 \u00d7 125 \n(e) 504 \u00d7 35 \nAnswer: \n(a) 728 \u00d7 101 = 728 \u00d7 (100 + 1) \n= 728 \u00d7 100 + 728 \u00d7 1 = 72800 + 728 = 73528 \n(b) 5437 \u00d7 1001 = 5437 \u00d7 (1000 + 1) \n= 5437 \u00d7 1000 + 5437 \u00d7 1 = 5437000 + 5437 = 5442437 \n(c) 824 \u00d7 25 = 824 \u00d7 (20 + 5) \n= 824 \u00d7 20 + 824 \u00d7 5 = 16480 + 4120 = 20600 \n(d) 4275 \u00d7 125 = 4275 \u00d7 (100 + 20 + 5) \n= 4275 \u00d7 100 + 4275 \u00d7 20 + 4275 \u00d7 5 = 427500 + 85500 + 21375 = 534375 \n(e) 504 \u00d7 35 = (500 + 4) \u00d7 35 \n= 500 \u00d7 35 + 4 \u00d7 35 = 17500 + 140 = 17640<\/p>\n

Question 5. \nStudy the pattern: \n1 \u00d7 8 + 1 = 9 \n12 \u00d7 8 + 2 = 98 \n123 \u00d7 8 + 3 = 987 \n1234 \u00d7 8 + 4 = 9876 \n12345 \u00d7 8 + 5 = 98765 \nWrite the next two steps. Can you say how the pattern works? \n(Hint: 12345 = 11111 + 1111 + 111 + 11 + 1) \nAnswer: \n123456 \u00d7 8 + 6 = 987654 \n1234567 \u00d7 8 + 7 = 9876543 \nPattern works like this: \n1 \u00d7 8 + 1 = 9 \n12 \u00d7 8 + 2 = 98 \n123 \u00d7 8 + 3 = 987 \n1234 \u00d7 8 + 4 = 9876 \n12345 \u00d7 8 + 5 = 98765 \n123456 \u00d7 8 + 6 = 987654 \n1234567 \u00d7 8 + 7 = 9875643<\/p>\n","protected":false},"excerpt":{"rendered":"
