Step-by-step explanation:
36. Similar fractions are fractions with same denominators.
37. 4/9 + 5/9 = 9/9 or 1
38. The LCD of ⅜, ½, and ¾ is 8.
39. 5 ⅔ + 4 ¼ = 9 11/12
40. 3/10 + 9/20 = 15/20. Therefore, 1 - 15/20 = 5/20 or ¼.
41. 5 ¾ - 1 ⅔ = 4 1/12
42. ₱1,000 - [(6×₱38.50)+(2×₱115.25)+(0.75×₱165)+(0.75×₱34)] = ₱389.25
43. √55 is an irrational number.
44. √119 lies between 10 and 11.
45. The principal root of √121 is 11.
46. False - Every decimal is an irrational number
47. -5, 0.5, √25 = 5, and 1/5 = 0.2. Therefore, the smallest number is -5.
48. Least to greatest: -10, -0.38, ½, √4
49. 49,000,000 × 79,000,000 = 3,871,000,000,000,000 or 3.871×10^15
50. 1.2×10³ = 1,200 and 4.5×10² = 450. Therefore, more people voted to continue the program of the school.
