Question 1

  • (12-3) ÷ (6-1) ? 4 • (20-3) - 4 • 3
  • 9 ÷ 5 ? 4 • 17 - 4 • 3
  • 1.8 ? 4 • (17 - 3)
  • 1.8 ? 4 • 14
  • 1.8 < 56

Question 2

  • (a) 0.8n = 12
  • (b) n = 12/0.8 = 15

Question 3

  • (a) c + 2.47 = 9.98
  • (b) c = 9.98 - 2.47 = 7.51
  • (c) c = 7.51 is the initial cost of the toy
