Final answer:
To express the comparison of 129 minutes to 3 hours as a reduced ratio, convert hours to minutes and simplify the ratio. The conversion results in 129 minutes to 180 minutes, which simplifies to a ratio of 43:60, which is the simplified final ratio.
Step-by-step explanation:
To write the comparison of 129 minutes to 3 hours as a ratio in lowest terms, we first need to convert hours to minutes, knowing that 1 hour is equal to 60 minutes. Therefore, 3 hours equals 3 × 60, which is 180 minutes. Now, we can write the ratio of 129 minutes to 180 minutes, which simplifies to:
129 ÷ 3 : 180 ÷ 3 = 43 : 60
This ratio cannot be simplified further, so the final simplified ratio is 43:60.
