Right Column (Problems 21–40) — *Find the missing number*

> 💡 Strategy: Subtract the known numbers from the total to find the missing addend.

21) 10 + ___ + 4 = 14.6
→ 10 + 4 = 14 → 14.6 - 14 = 0.6

22) 70 + 8 + ___ = 78.7
→ 70 + 8 = 78 → 78.7 - 78 = 0.7

23) 100 + 52 + ___ = 152.2
→ 100 + 52 = 152 → 152.2 - 152 = 0.2

24) 0.3 + ___ + 200 = 240.3
→ 0.3 + 200 = 200.3 → 240.3 - 200.3 = 40

25) 0.6 + 90 + ___ = 96.6
→ 0.6 + 90 = 90.6 → 96.6 - 90.6 = 6

26) 52 + ___ + 100 = 152.7
→ 52 + 100 = 152 → 152.7 - 152 = 0.7

27) 30 + 0.8 + ___ = 230.8
→ 30 + 0.8 = 30.8 → 230.8 - 30.8 = 200

28) 70.5 + 100 + ___ = 172.5
→ 70.5 + 100 = 170.5 → 172.5 - 170.5 = 2

29) 200 + 50.6 + ___ = 259.6
→ 200 + 50.6 = 250.6 → 259.6 - 250.6 = 9

30) ___ + 6.7 + 100 = 176.7
→ 6.7 + 100 = 106.7 → 176.7 - 106.7 = 70

31) 8.3 + ___ + 40 = 848.3
→ 8.3 + 40 = 48.3 → 848.3 - 48.3 = 800

32) 80 + 300 + ___ = 382.4
→ 80 + 300 = 380 → 382.4 - 380 = 2.4

33) 600 + 90 + ___ = 698.6
→ 600 + 90 = 690 → 698.6 - 690 = 8.6

34) 720 + ___ = 727.9
→ 727.9 - 720 = 7.9

35) ___ + 130 = 135.7
→ 135.7 - 130 = 5.7

36) 200 + ___ = 247.6
→ 247.6 - 200 = 47.6

37) 700 + ___ = 781.3
→ 781.3 - 700 = 81.3

38) ___ + 8 = 68.2
→ 68.2 - 8 = 60.2

39) 9 + ___ = 129.5
