We could draw a table to help us to answer this question.

Took medication Didn't take medication Total
No cough 17 28 45
Cough 13 42 55
Total 30 70 100

The question states "given that they reported no cough", which is basically asking how many people OUT OF those who reported no cough took the medication.

So using the table, the number of people who took the medication and reported no cough is 17. The TOTAL number of people who reported no cough is 45. 17/45 = 37.777 = 38%

Answer:

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Step-by-step explanation:

Given

$\frac{1}{4}$

$\frac{5}{10}$

$\frac{1}{2}>\frac{1}{3}$

$\frac{4}{8}>\frac{2}{6}$

$\frac{3}{5}>\frac{4}{5}$

Required

Select the unit fractions

<em>If we are to go by what a unit fraction means: it means that the numerator of the fraction must be 1 and must be written as a single fraction i.e. </em> $\frac{1}{2}$ <em> and not as an inequality i.e. </em> $\frac{3}{5}>\frac{4}{5}$ <em />

<em>Given the format of the question, what is required of the question is to </em><em>select all correct inequality.</em>

<em></em>

$(a)$ $\frac{1}{4}$

Convert to decimals

$0.25 < 0.167$ ---- This is not true because $0.25 > 0.167$

$(b)$ $\frac{5}{10}$

Convert to decimals

$0.5 < 0.5$ ---- This is not true because $0.5 = 0.5$

$(c)$ $\frac{1}{2}>\frac{1}{3}$

Convert to decimals

$0.5 > 0.33$ ---- This is true

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Convert to decimals

$0.5 > 0.33$ ---- This is true

$(e)$ $\frac{3}{5}>\frac{4}{5}$

$0.6 > 0.8$ --- This is not true because $0.6 < 0.8$

So: the true inequality is:

$(d)$ $\frac{4}{8}>\frac{2}{6}$
