Question

There are 100 cm in 1 m and 1000 m in 1 km. You need a curtain for a window that is 156 cm wide.

(a) If you wanted to convert the width to kilometers, what conversion factor should you use? Show your work.
(b) What is the width in kilometers?

Answer 1

For letter a.) If I wanted to convert the width to kilometers, I would use the conversion factor:
156 cm to m, them m to km
156cm*(1m/100cm)=1.56m
1.56m*(1km/1000m) = 0.00156 km

For the letter b.) The width in kilometer is 0.00156 km.
