Question

The world produces about 3.9 billion tons of food every year. Of that amount, approximately 2.6 billion tons is consumed each year. The rest is wasted. What percentage of food is wasted every year?

Answer 1

33.3%

3.9-2.6= 1.3 billon tons of food wasted

1.3/3.9= 0.333

=33.3%

Answer 2

`33(1)/(3)` %

Step-by-step explanation:

3.9 - 2.6 = 1.3

`(1.3)/(3.9) :(y)/(100)`

y × 3.9 = 1.3 × 100

3.9y = 130

3.9y ÷ 3.9 = 130 ÷ 3.9

`y=33(1)/(3)`
