Answer:

18. 20:30

19. 20:25

20. 27:18

Step-by-step explanation:

18. If there are 50 students and 20 students are boys then, 50 - 20= 30 so, 30 students are girls.

20 boys to 30 girls or 20:30

19. 30 girls minus 5 girls that are absent, equal to 25. Then, 20 boys to 25 girls or 20:25

20. 20 boys minus 2 boys that are absent, equal to 18. 30 girls minus 3 girls that are absent, equal to 27, so, 27 girls to 18 boys or 27:18
