Question

Myriah wants to use dimensional analysis to find out how many centimeters (cm) are in 1.4 meters (m). Which of these equalities will be useful for this calculation?

2.54 cm = 1 in.
1 m = 39.37 in.
1 cm = 10 mm
100 cm = 1 m

Answer 1

100cm = 1m

Explanation:

centi means 10^-2, so there would be a greater amount of centimeters to match meters. Also the problem in question is talking about cm to m and that option would be the only one that appropriately has those two values.

Answer 2

I believe the correct answer from the choices listed above is the last option. The equality that will be useful for Myriah's calculation would be 100 cm = 1 m. She just needs to convert her value from meters to centimeters. A conversion factor is all she needs.
