SA2 Practice Paper - Whole Numbers (Version 1 of 5)

Section A

Question 1 (a) 6 402 050 (b) The digit 4 is in the hundred thousands place, so its value is 400 000.

Question 2 (a) Nearest thousand: 7 468 295 → 7 468 000 (b) Nearest ten thousand: 7 468 295 → 7 470 000

Question 3 $24 + 18 \div 6 \times 5 - 7 = 24 + 3 \times 5 - 7 = 24 + 15 - 7 =$ 32

Question 4 $84 = 2 \times 42$ , $126 = 3 \times 42$ . GCF = 42 (Check: $84 = 2^2 \times 3 \times 7$ , $126 = 2 \times 3^2 \times 7$ ; common factors $2 \times 3 \times 7 = 42$ .)

Question 5 LCM of 12 and 18 = 36 minutes. 08:45 + 36 min = 09:21

Section B

Question 6 $1\,275 \times 24 =$ 30 600 toys

Question 7 $3\,840 \div 16 =$ 240 stamps per album

Question 8 $(1\,500 + 96) \div 14 = 1\,596 \div 14 =$ 114

Question 9 $245 \times 18 =$ $4 410

Question 10 After buying the bicycle, remainder $= 95 \times 2 = 190$ . Money at first $= 190 + 128 =$ $318

Section C

Question 11 Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Question 12 Pages in one hour: $385 \times 60 = 23\,100$ . Books: $23\,100 \div 120 = 192$ remainder 60. 192 complete books

Question 13 Two numbers with product 216 and sum 35: 8 and 27 ( $8 \times 27 = 216$ ; $8 + 27 = 35$ )

Question 14 LCM of 8, 12, 20 = 120 seconds = 2 minutes. Next ring together: 09:02

Question 15 Greatest: 7 520. Smallest: 2 057. Difference: $7\,520 - 2\,057 =$ 5 463

Question 16 $45\,\text{kg} = 45\,000\,\text{g}$ . $45\,000 \div 850 = 52$ remainder 800. 52 full days, with 800 g remaining.

Question 17 $n \equiv 4 \pmod{9}$ and $n \equiv 3 \pmod{11}$ . Testing $n = 4, 13, 22, 31, 40, 49, \mathbf{58}$ : $58 \div 9 = 6$ r 4; $58 \div 11 = 5$ r 3. Smallest number of chairs = 58

Question 18 Let Ben = 1 unit. Ali = 2 units, Calvin = 3 units. Total = 6 units = 720, so 1 unit = 120. Ali = 240, Ben = 120, Calvin = 360

Question 19 Buying 30 pens gives 6 free pens: $30 + 6 = 36$ . Cost $= 30 \times \$ 3 = $**$ 90**

Question 20 Sticks in Figure $n$ : $3n + 1$ . (a) Figure 50: $3 \times 50 + 1 =$ 151 sticks (b) $3n + 1 = 100 \Rightarrow 3n = 99 \Rightarrow n = 33$ . Figure 33
