Answer: 3 : 2 : 1 = 900 : 600 : 300

since the order are: guava, lanzones and guyabano, it makes the guava (3), lanzones (2) and guyabano as (1)

900 guava trees

600 lanzones trees

300 guyabano trees

Step-by-step explanation:

3 + 2 + 1 = 6

1800 divided by 6 = 300

300 x 3 = 900

300 x 2 = 600

300 x 1 = 300

To check if it’s correct:

900 + 600 + 300 = 1800

1800 = 1800 trees
