Answer:
2 people ordered salah
Step-by-step explanation:
#Total number of people in the class = 40
#Number of people who ordered chicken= 1/5 of the total number of people;
that is, ⅕×40=8
therefore 8 people ordered chicken.
#Number of people who ordered hamburgers= ¾of the total number of people.
that is; ¾×40=30
therefore 30 people ordered hamburgers.
#Number of people who ordered salad= total number of people - the sum of people who ordered chicken and hamburgers.
that is,
40 - ( 30 + 8 ),.
40 - 38 = 2
