Final answer:
Upon simplifying, both ratios 3:8 and 9:24 reduce to the same fraction, 3/8, which confirms that the two ratios are equivalent.
Step-by-step explanation:
To determine whether the ratios 3:8 and 9:24 are equivalent, we can compare them by converting each ratio into a fraction and then simplifying each to see if they are the same. First, write the ratio 3:8 as a fraction: 3/8. Now, write the second ratio 9:24 as a fraction: 9/24. The next step is to simplify 9/24 by dividing both the numerator and the denominator by their greatest common divisor, which is 3. This simplifies to 9÷3 / 24÷3, which equals 3/8. Since both simplified fractions are equal, we can conclude that the ratios 3:8 and 9:24 are indeed equivalent.
