Question

Audra's paper airplane is 13.8 centimeters long. Jordan's paper airplane is 9/10 centimeters shorter than Audra's. How long is Jordan's paper airplane?

Answer 1

If Audra's airplane is 13.8 centimeters long, and Jordans airplane is 9/10 centimeters shorter than Audra's. First multiply 13.8 with 9/10, which equals 12.42, next subtract 13.8 and 12.42 which equals 1.38. So Jordan's airplane is I believe 1.38 centimeters long.
