1) 2a, when a = 5
→ 2 × 5 = 10

2) b + 7, when b = 12
→ 12 + 7 = 19

3) c – 5, when c = 21
→ 21 – 5 = 16

4) d ÷ 3, when d = 24
→ 24 ÷ 3 = 8

5) e + 12, when e = 19
→ 19 + 12 = 31

6) f – 15, when f = 100
→ 100 – 15 = 85

7) 7g, when g = 8
→ 7 × 8 = 56

8) ½ h, when h = 56
→ Half of 56 = 56 ÷ 2 = 28

9) i ÷ 5, when i = 20
→ 20 ÷ 5 = 4

10) 20 – j, when j = 18
→ 20 – 18 = 2

11) 30 ÷ k, when k = 6
→ 30 ÷ 6 = 5

12) l / 2, when l = 50
→ 50 ÷ 2 = 25

13) 10m, when m = 34
→ 10 × 34 = 340

14) n – 25, when n = 72
→ 72 – 25 = 47

15) ¼ o, when o = 32
→ One fourth of 32 = 32 ÷ 4 = 8

16) 4 – p, when p = 0.5
→ 4 – 0.5 = 3.5

17) 1.5 + q, when q = 2.7
→ 1.5 + 2.7 = 4.2

18) 3r, when r = 0.7
→ 3 × 0.7 = 2.1

19) s – 0.7, when s = 3
→ 3 – 0.7 = 2.3

20) ½ t, when t = 7
→ Half of 7 = 7 ÷ 2 = 3.5
