Question

are the ratios 3:1 and 15:5 equivalent? yes no

Explanation:

Step1: Simplify 15:5

To simplify a ratio, divide both parts by their greatest common divisor. The GCD of 15 and 5 is 5. So, $\frac{15}{5}:\frac{5}{5} = 3:1$.

Step2: Compare with 3:1

The simplified form of 15:5 is 3:1, which matches the first ratio.

Answer:

yes (the "yes" option is correct as simplifying 15:5 gives 3:1, making the ratios equivalent)
