RATIO WORD PROBLEM

Question

A recipe calls for orange juice and pop in the ratio of 2:5. The recipe requires 1 L of pop to serve 7 people. How much orange juice is needed for 7 people?

How much orange juice and pop needed to serve 15 people? 20 people?

Answer 1

1/7 liter of soda pop servers 1 person

2x + 5(1/7) = 1

2x + 5/7 = 1

2x = 2/7

x = 1/7

2/7 liters of juice and 5/7 liters of pop serves 1 person

2 liters of juice and 5 liters of pop serves 7 people

15/7 = 2 and 1/7

(2)(15/7) liters of juice and (15/7)(5) liters of pop serves 15 people

That;s 30/7 and 75/7 liters of each

20/ 7 = 2 and 6/7

(2)(20/7) liters of juice and (20/7)(5) liters of pop serves 20 people

That's 40/7 and 100/7 liters of each
