Answer:
19. A
20. D.
21. C.
Step-by-step explanation:
19. adults = the number of all people - number of children - number of teens
adults = 12 - 12(¼) - 12(½)
adults = 12 - 3 - 6
adults = 3 people
20. kilogram of government = total number of kg og rice donated - from school - from generous citizen
government = 1200½ - 289⅚ - 365¾
government = 2401/2 - 1739/6 - 1463/4
government = 14406/12 - 3478/12 - 4389/12
government = 6539/12
government = 544 11/12
21. total cup of flour in the container = cup of flour in container took + cup of flour in container left
total = 5¾ + 2½
total = 23/4 + 5/2
total = 23/4 + 10/4
total = 33/4
total = 8 1/4
