Answer 1

1. Which of the following statements refers to the relative quantities and which refer to absolute quantities?

i. In 2017, the number of first-year University students registered for a mathematics course was 20 317. (absolute quantities because we know how many students come to the mathematic course)

ii. More than half of students at a.Gauteng University are women. (absolute quantities because we have results of statistical information)

iii. The death toll from Cyclone Dineo might reach 10 000. (relative quantities, we do not have real information about this situation)

iv. The ratio of female to male workers in the mines is 1:9. (relative quantities because information about absolute quantities is not full).

v. A couple has a 20% chance of conceiving a child during any given month.(relative quantities because not full information about quantity of conceiving)

vi. One out of every 10 people is left-handed.(absolute quantities, this is the result on a statistic experiment)

2. A biscuit recipe requires 2/3 of a cup of milk. Each recipe makes 12 biscuits. How many biscuits can 6 cups of milk make?

$$6/ \frac{2}{3}=9$$

$$12\times9=108$$
