3. Pop Quiz!
Edited on Tue Oct-13-09 12:57 PM by DontTreadOnMe
OK, simple math. (HINT - please note the amounts are not the same in each question and each question will have a unique answer)

Question 1: Add the following 5 amounts: 10.4mm + 12.6mm + 5.5mm + 9.8mm

Question 2" Add the following 5 amounts: 10 3/8" + 12 7/16" + 5 1/2" + 9 15/16"

Which one was easier?

Shall we try division next?
