I'll work through each day's problems step by step, checking my calculations carefully.
MONDAY:
1. 8 × 12 = 96 (8 × 10 = 80, plus 8 × 2 = 16, so 80 + 16 = 96)
2. 54 ÷ 9 = 6 (because 9 × 6 = 54)
3. 112 + 72 = 184 (100 + 70 = 170, plus 12 + 2 = 14, so 170 + 14 = 184)
4. 86 - 32 = 54 (80 - 30 = 50, plus 6 - 2 = 4, so 50 + 4 = 54)
5. 3:15pm + 70 minutes = 4:25pm (3:15 + 45 min = 4:00, then + 25 more = 4:25)
6. 2/5 of 30 = 12 (30 ÷ 5 = 6, then 6 × 2 = 12)
7. Shape has 6 squares total, 1 is shaded = 1/6
8. Round to nearest 100: 450 rounds to 500
9. 5m = 500cm (multiply by 100)
10. Pattern: 5, 25, 45... adding 20 each time, so next is 65
TUESDAY:
1. 5 × 11 = 55
2. 96 ÷ 12 = 8 (because 12 × 8 = 96)
3. 145 + 62 = 207 (140 + 60 = 200, plus 5 + 2 = 7, so 200 + 7 = 207)
4. 240 - 110 = 130
5. 2:15am + 80 minutes = 3:35am (2:15 + 45 = 3:00, then + 35 = 3:35)
6. 2/8 of 16 = 4 (16 ÷ 8 = 2, then 2 × 2 = 4)
7. Shape has 6 squares total, 3 are shaded = 3/6 or 1/2
8. Round to nearest 100: 720 rounds to 700
9. 2.2m = 220cm (2.2 × 100 = 220)
10. Pattern: 4.5, 4.1, 3.7... subtracting 0.4 each time, so next is 3.3
WEDNESDAY:
1. 9 × 7 = 63
2. 28 ÷ 4 = 7
3. 96 + 96 = 192
4. 91 - 60 = 31
5. 4:20pm + 55 minutes = 5:15pm (4:20 + 40 = 5:00, then + 15 = 5:15)
6. 1/5 of 60 = 12 (60 ÷ 5 = 12)
7. Shape has 6 squares total, 4 are shaded = 4/6 or 2/3
8. Round to nearest 100: 3,120 rounds to 3,100
9. 200cm = 2m (divide by 100)
10. Pattern: 99, 97, 95... subtracting 2 each time, so next is 93
THURSDAY:
1. 8 × 6 = 48
2. 49 ÷ 7 = 7
3. 45 + 47 = 92 (40 + 40 = 80, plus 5 + 7 = 12, so 80 + 12 = 92)
4. 365 - 125 = 240
5. 1:50am + 40 minutes = 2:30am (1:50 + 10 = 2:00, then + 30 = 2:30)
6. 3/4 of 24 = 18 (24 ÷ 4 = 6, then 6 × 3 = 18)
7. Shape has 6 squares total, 2 are shaded = 2/6 or 1/3
8. Round to nearest 100: 2,850 rounds to 2,900
9. 450cm = 4.5m (450 ÷ 100 = 4.5)
10. Pattern: 0.3, 0.5, 0.7... adding 0.2 each time, so next is 0.9
Final Answer:
Monday: 1. 96, 2. 6, 3. 184, 4. 54, 5. 4:25pm, 6. 12, 7. 1/6, 8. 500, 9. 500cm, 10. 65
Tuesday: 1. 55, 2. 8, 3. 207, 4. 130, 5. 3:35am, 6. 4, 7. 3/6 (or 1/2), 8. 700, 9. 220cm, 10. 3.3
Wednesday: 1. 63, 2. 7, 3. 192, 4. 31, 5. 5:15pm, 6. 12, 7. 4/6 (or 2/3), 8. 3,100, 9. 2m, 10. 93
Thursday: 1. 48, 2. 7, 3. 92, 4. 240, 5. 2:30am, 6. 18, 7. 2/6 (or 1/3), 8. 2,900, 9. 4.5m, 10. 0.9
