Kristine is 5 1/2 feet tall. Her sister Colleen is 57 inches tall. How many inches taller is Colleen?

Question

Coversion

Answer 1

Hello Abigail!

 

For this problem you first need to convert the units to either be both in feet, or both in inches.  Let's change 5.5 feet into inches.  5 1/2 times 12 = 66.  Now subtract Colleen's height (57 inches) from Kristine's height (66 inches).  Looks like Colleen is shorter than Kristine by 9 inches, or Kristine is 9 inches taller than Colleen.
