Karnataka State Syllabus Class 6 Maths Chapter 2 Whole Numbers Ex 2.3<\/h2>\n

Question 1.
\nWhich of the following will not represent zero:
\na) 1 + 0
\nb) 0 \u00d7 0
\nc) \\(\\frac{0}{2}\\)
\nd) \\(\\frac{10-10}{2}\\)
\na) 1 + 0 = 1 It does not represent zero
\nb) 0 \u00d7 0 = 0 It represent zero
\nc) \\(\\frac{0}{2}=0\\) It represents zero
\nd) \\(\\frac{10-10}{2}=\\frac{0}{2}=0\\) It represent zero
\nSolution:
\na) 1 + 0 = 1<\/p>\n

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.
\nSolution:
\nIf the product of 2 whole numbers is zero, then one of them is definitely zero,
\nFor example, 0 \u00d7 2 =0 and 17 \u00d7 0 = 0
\nIt the product of 2 whole numbers is zero them both of them may be zero 0 \u00d7 0 = 0
\nHowever, 2 \u00d7 3 = 6
\n(Since number to be multiplied are not equal to zero, the result of the product will also be non-zero.<\/p>\n

Question 3.
\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:
\nIf the product of 2 numbers is, then both the numbers have to be equal to 1
\nFor example ,1 \u00d7 1 = 1 However, 1 \u00d7 6 = 6
\nClearly, the product of two whole numbers will be 1 in the situation when both numbers to be multiplied are 1.<\/p>\n

Question 4.
\nFind using distributive property:
\na) 728 \u00d7 101
\nb) 5437 \u00d7 1001
\nc) 824 \u00d7 25
\nd) 4275 \u00d7 125
\ne) 504 \u00d7 35
\nSolution:
\na) 728 \u00d7 101 = 728 \u00d7 (100+1)
\n= 728 \u00d7 100 + 728 + 1
\n= 72800 + 728 = 73528<\/p>\n

b) 5437 \u00d7 1001 = 5437 \u00d7 (1000 + 1)
\n= 5437 \u00d7 1000 + 5437 \u00d7 1
\n= 5437000 + 5437 = 5442437<\/p>\n

c) 824 \u00d7 25 = (800 + 024) \u00d7 25
\n= (800 + 25 – 1) \u00d7 25
\n= 800 \u00d7 25 + 25 \u00d7 25 – 1 \u00d7 25 = 20000 + 625 – 25
\n= 20000 + 600 = 20600<\/p>\n

d) 4275 \u00d7 125
\n= (4000 + 200 + 100 – 25 ) \u00d7 125 = 4000 \u00d7 125 + 200 \u00d7 125 + 100 + 125 – 25 \u00d7 125
\n= 500000 + 25000 + 12500 – 3125
\n= 534375<\/p>\n

e) 504 \u00d7 35 = ( 500 + 4) \u00d7 35
\n= 500 \u00d7 35 + 4 \u00d7 35
\n= 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).
\nSolution
\n123456 \u00d7 8 + 6 = 987648 + 6 = 987654
\n1234567 \u00d7 8 + 7 = 9876536 + 7 = 9876543
\nYes, the pattern works.
\nAs 123456= 111111 + 11111 + 1111 + 111 + 11 + 1.
\n123456 \u00d7 8 = ( 111111 + 11111 + 1111 + 111 + 11 + 1) \u00d7 8
\n= 111111 \u00d7 8 + 11111 \u00d7 8 + 1111 \u00d7 8 + 111 \u00d7 8 + 11 \u00d7 8 + 1 \u00d7 8
\n= 888888 + 88888 + 8888 +888 + 88 + 8 = 987648
\n= 123456 \u00d7 8 + 6 = 987648 + 6 = 987654<\/p>\n","protected":false},"excerpt":{"rendered":"
