Answer 3

To solve this problem, we can use the concept of ratios and proportions.

We have: 27 dm : 9 cm

Since 1 decimeter (dm) is equal to 10 centimeters (cm), we can convert the measurements to the same unit:

27 dm = 27 * 10 cm = 270 cm

Now the ratio becomes: 270 cm : 9 cm

To simplify the ratio, we can divide both sides by their greatest common divisor, which is 9:

270 cm ÷ 9 = 30 cm 9 cm ÷ 9 = 1 cm

So, the simplified ratio is: 30 : 1

This means that 27 dm is equivalent to 270 cm, which simplifies to the ratio 30 : 1.
