Question

there are 40 people in a resturant 1/5 of the people ordered chicken while 3/4 of them ordered hamburgers the rest ordered salad how many people ate salad.

Answer 1

2 people ordered salah

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
