Question

A dollar bill is 15.6 cm long. If 200 dollar bills were laid end to end, how many meters long would the line be?

Answer 1

31.2 meters

Explanation:

If 1 dollar bill is 15.6 cm long, 200 dollar bills would be `15.6*200` cm long (laid end to end).

`15.6*200=3120 rarr` 3120 cm

cm to meters: 100 cm per 1 meter

To convert meters into centimeters, multiply by 100. To convert centimeters into meters, divide by 100.

`3120/100=31.2`
