Final answer:
All of the given scenarios can be represented by a ratio.
Step-by-step explanation:
In all of the given scenarios, we can represent the ratios in a similar way.
A) 2 in every 5 people wear glasses, which can be written as 2:5.
B) For every £1 Whitney has, Mo has £1.50, which can be written as 1:1.5.
C) For every 225 g of flour, there are 150 g of sugar, which can be written as 225:150.
Therefore, the answer is D) All of the above, as each scenario can be represented by a ratio.
While these ratios are in different numerical forms, they all represent proportional relationships between two quantities. However, they do not represent the exact same proportions and are therefore not identical ratios.
