Question

Tia measured a greeting card and found that it was 1 decimeter long. How many centimeters are in 1 decimeter?

Answer 1

10 cm

Explanation:

1 decimeter is equal to 10⁻¹ meters.

1 meter is equal to 10² centimeters. We can use a conversion fraction to find the centimeters corresponding to 10⁻¹ meters.

10⁻¹ m × (10²cm/1 m) = 10 cm

1 dm = 10⁻¹ m

10⁻¹ m = 10 cm

Due to the transitive property, 1 decimeter is equal to 10 centimeters.
