2. The number of adults who live in the house is <em>3</em><em> </em>(1,200/400).
3.a. If an adult recycled the <em>glass, paper, and card</em> that have 42% of the rubbish, the adult will generate 232 kg (400 kg x (1 - 42%) of rubbish.
b. If the adult, in addition, had a <em>composite for vegetable and decomposable material</em>, he will generate 152 kg (400 kg x (1 - 62%).
Data and Calculations:
1 ton = 1,000 kg
Weight of rubbish produced by an adult per year = 400 kg
Total kg of rubbish produced by the family = 1,200 kg (1,000 x 1.2)
Percentage of Vegetable and decomposable material = 20%
Percentage of glass, paper, and card = 42% (33% + 9%)

Answer:
7 7/12 pounds of fruit
Step-by-step explanation:
First, add all of the whole numbers
2 + 1 + 3= 6 (save for later)
then find a common denominator between the fractions which is 12
1/3 = 4/12
5/6 = 10/12
4/12 + 10/12 + 5/12 = 19/12 or 1 7/12
now, add 1 7/12 + 6 to get you 7 7/12
