Final answer:
No, the given ratios are not proportional. To determine if the given ratios are proportional, we need to set up a proportion by setting the two ratios equal to each other.
Step-by-step explanation:
To determine if the given ratios are proportional, we need to set up a proportion by setting the two ratios equal to each other. In this case, the ratios are 4/7 and 12/28:
4/7 = 12/28
To simplify the proportion, we can cross multiply:
4 * 28 = 7 * 12
112 = 84
Since 112 is not equal to 84, the two ratios are not proportional.
