Respuesta :

Question 1: True, the given ratio is 4:5 so for every 5 girls, there are 4 boys.

Question 2: False, 4/9 of the students in the school are boys. Because the ratio is 4:5, we can add them together to get the total ratio of students.

Question 3: True, if there are 270 students with a ratio of 4 boys:5 girls, there must be 120 boys and 150 girls.

Question 4: False, see Question 3

Question 5: True, see Question 2
