1. You have articulated the approach very clearly, on how to go about converting the numbers in the ratio. For (a)(i), "30:48" is not the simplest form

2. For (b), you have articulated the reason for the multiplication, i.e. so that we can "make comparison of the pairs".

3. For (b), why do we multiply the ratio by 16? How did you arrive at this figure?

4. For (c), how did you arrive at the figure 119? Also, why divide $500 by this figure?

sorry my voice was cut off at the end by the blog. What i meant to say was " and the answer is 63.03"
