Answer:
Q5: 760 000 tonnes were recycled. Q6: There were 108 000 female centenarians.
Explanation:
Q5:
2 000 000 tonnes * 0.38 = 760 000 tonnes
Q6:
There were 135 000 centenarians.
The ratio of male to female is 1:4 so in other words 1/5 of all are male and 4/5 of all are female. 4/5 can be written as 0.8
135 000 * 0.8 = 108 000
