Answer 1

Example 1: From house-hold life;

If person need half a liter of milk and three eggs per day, how many liters of milk and number of eggs the person needs in a week?

A: Start by milk:

1 person ; 1/2 a liter of milk per day

7 person's days ; x liters of milk per week

Therefore, x = 7 x (1/2) / 1 = 3.5 liters/week

B: Then the eggs:

1 person ; 3 eggs per day

7 person's days ; x eggs per week

Therefore, x = 7 x 3 / 1 = 21 eggs per week
