\nWhich of the following will not represent zero:
\n(a) 1 + 0
\n(b) 0 x 0
\n(c) \\(\\frac { 0 }{ 2 }\\)
\n(d) \\(\\frac { 10-10 }{ 2 }\\)
\nSolution:
\n(a) 1 + 0 = 1 \u2260 0, does not represent zero.
\n(b) 0 x 0 = 0, represents zero
\n(c) \\(\\frac { 0 }{ 2 }\\) = 0, represents zero.
\n(d) \\(\\frac { 10-10 }{ 2 }\\) = \\(\\frac { 0 }{ 2 }\\) = 0 represents zero.<\/p>\n
\nIf the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through examples.
\nSolution:
\nYes, Examples:
\n5 x 0 = 0
\n0 x 8 = 0
\n0 x 0 = 0<\/p>\n
\nIf the product of two whole numbers is 1, can we say that one or both of them will be 1? Justify through examples.
\nSolution:
\nThis is only true, when each of the number are 1.
\n1 x 1 = 1<\/p>\n
\nFind using distributive property:
\n(\u0430) 728 x 101
\n(b) 5437 x 1001
\n(c) 824 x 25
\n(d) 4275 x 125
\n(e) 504 x 35
\nSolution:
\n(a) 728 x 101 = 728 x (100 + 1)
\n= 728 x 100 + 728 x 1
\n= 72800 + 728
\n= 73528<\/p>\n
\n= 5437 x 1000 + 5437 x 1
\n= 5437000 + 5437
\n= 5442437<\/p>\n
\n= 824 x 20 + 824 x 5
\n= 16480 + 4120
\n= 20600<\/p>\n
\n= 4275 x 100 + 4275 x 20 + 4275 x 5
\n= 427500 + 85500 + 21375
\n= 534375<\/p>\n
\n= 500 x 35 + 4 x 35
\n= 17500 + 140
\n= 17640<\/p>\n
\nStudy the pattern:
\n1 x 8 + 1= 9
\n12 x 8 + 2 = 98
\n123 x 8 + 3 = 987
\n1234 x 8 + 4 = 9876
\n12345 x 8 + 5 = 98765
\nWrite the next two steps. Can you say how the pattern works?
\nSolution:
\nStep I: 123456 x 8 + 6 = 987654
\nStep II: 1234567 x 8 + 7 = 9876543<\/p>\n
\n(1) x 8 + 1 = 9
\n(12) x 8 + 2 = (11 + 1) x 8 + 2 = 98
\n(123) x 8 + 3 = (111 + 11 + 1) x 8 + 3 = 987
\n(1234) x 8 + 4 = (1111 + 111 + 11 + 1) x 8 + 4 = 9876
\n(12345) x 8 + 5 = (11111 + 1111 + 111 + 11 + 1) x 8 + 5 = 98765<\/p>\n
