Answer:
2/3
Step-by-step explanation:
Given that:
Number of students = 80
Number of parents = 40
fraction of the ratio of students to the total number of people at the graduation
Total number of people at graduation =. (number of students + number of parents)
80 + 40 = 120
Number of students : total people
80 : 120
80/120 = 8/12 = 2/3
x = 129
y = 82
x + 51 = 180
x = 180 - 51
y + 51 + 47 = 180
y = 98 - 180
cool
7 because 12 is more than the half of 16 (8)
