6 4 Estimate and calculate 113 a) V 4 = {4, 8, 12, 16, 20, 24, 28, 32, ...} b) V 3 = {12, 15, 18, 21, 24} c) V 6 = {…, 36, 42,…, 60,…, 240,…, 2 718,…} d) V 4 = {4, 8, 12} 114 a) T 12 = {1, 2, 3, 4, 6, 12} b) T 20 = {1, 2, 4, 5, 10, 20} c) T 35 = {1, 5, 7, 35} 115 a) Correct, because 7 is contained in 14 without a remainder. b) Wrong, 5 | 20 because 5 is in 20 with no remainder. c) Wrong, because 3 is not contained in 16 without a remainder. d) Correct, because 4 is not contained in 26 without a remainder. 116 a) 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68 b) 77, 81, 85, 89, 93, 97, 101, 105, 109, 113, 117, 121, 125 117 a) 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56 b) 21, 23, 25, 27, 29, 31, 33 , 35, 37, 39, 41, 43, 45, 47 118 a) Compare with the example! For example: The “supplementary number” is an even number. b) Compare with the sample! For example: The “supplementary number” is an odd number. 119 a) and b) Even numbers: 2, 6, 10, 14, 18, 50 odd numbers: 1, 3, 5, 7, 9, 25 c) Eg: If the odd number is doubled, you get the even number. 2 u = g 120 121 a) 407 000 = 4HT 7T b) 1 014 = 1T 1 Z 4 E c) 323 = 3H 2 Z 3 E 122 ZB: a) Do not round, only the correct joker number brings a profit. b) ≈ 90,000 spectators, round because an approximation is sufficient. c) Do not round because the year of birth is an exact specification. d) ≈ 3,000 km, round because an approximate value is sufficient. 123 a) b) c) Compare with the number lines from above! Mark the numbers 5 (predecessor of 6) and 11 (successor to 10)! 124 a) DCCLIII b) 1928 c) MCDXCII d) 76 125 a) and b) 67 450
