3rd Grade (mixed)
1. 33 kits left.
8 × 7 = 56. Then 56 − 23 = 33.
2. 9 groups; 5 students in the last.
69 ÷ 8 = 8 r 5. Everyone must be seen → 9 groups, last has 5.
3. 205 bandages.
254 − 137 = 117. Then 117 + 88 = 205.
4. 11:50 a.m.
40 + 15 + 35 = 90 minutes = 1 hr 30. 10:20 + 1:30 = 11:50 a.m.
5. 7 complete stations, 3 gloves left.
45 ÷ 6 = 7 r 3. Complete sets only → 7, with 3 gloves spare.
4th Grade (mixed)
1. 36 test tubes per bench.
18 × 24 = 432. Then 432 ÷ 12 = 36.
2. Drunk 11/15; 4/15 left.
Common bottom 15. 1/3 = 5/15, 2/5 = 6/15. 5/15 + 6/15 = 11/15. Left: 15/15 − 11/15 = 4/15.
3. Area 756 sq m; 14 wards.
42 × 18 = 756. Then 756 ÷ 54 = 14.
4. 25,200 beats; 4,800 more will fit.
4,200 × 6 = 25,200. Then 30,000 − 25,200 = 4,800.
5. 85 hours with patients.
9 × 14 = 126 hours. Then 126 − 26 − 15 = 85.
