Step-by-step explanation:
24.
Problem:
What percent of the class attended the meeting?
OR
What percent of 40 is 36?
25.
Solution ad answer:
36 = number of pupils who had attended the class
40 = total number of pupils in the class
36/40
= (36÷4) / (40 ÷4)
= 9/10
= 0.9 X 100
= 90%
26. C
27. A
28. B
29. D
30. A
(24 - 9) + (12 - 7) X 3^2
= (15) + (5) X 9
= 15 + 45
= 60
31. D
32. A
12 + 25 ÷ 5 X 3 + 300
= 12 + 5X 3 + 300
= 12 + 15 +300
= 27 + 300
= 327
33. B
12 - 3 + 18 ÷ 6 X 3
= 9 + 3 X 3
= 9 + 9
= 18
