If six out of 15 customers order a chicken sandwich, how many chicken sandwiches should a restaurant predict they will need to serve 270 people?108
270
90
120

Answers

Given:
6 out of 15 customers order a chicken sandwich
270 customers

This is a problem of ratio and proportion:

a/b = c/d where ad = bc
6/15 = x/270
6 * 270 = 15x
1,620 = 15x
1620 / 15 = x
108 = x

The restaurant should predict to serve 108 chicken sandwich to the 270 people.

Answer:

108 = x

Step-by-step explanation:

mark me brainy plz!

a/b = c/d where ad = bc

6/15 = x/270

6 * 270 = 15x

1,620 = 15x

1620 / 15 = x
