you can set ratios up the same way you can fractions: (let's just say for now that they are equal) [tex] \frac{16}{12} = \frac{64}{60} [/tex] simplify the fractions and you get: [tex] \frac{4}{3} = \frac{16}{15} [/tex] That isn't true, so [tex] \frac{4}{3} \neq \frac{16}{15} [/tex] so your answer is no, 16:12 and 64:60 are not equivalent
