Worked solution

1. Determine the number of units for each shop from the bar graph

Shop A = 16 units
Shop B = 18 units
Shop C = 12 units
Shop D = 20 units

2. Calculate the total number of units sold by all shops

Total units = $16 + 18 + 12 + 20 = 66$

3. Express Shop B's sales as a fraction of the total and simplify

Fraction = $\frac{18}{66} = \frac{3}{11}$

Answer

$\frac{9}{33}$ or $\frac{3}{11}$
