Answered by Ms. Sue
You're right as far as you went. :-) Now reduce 10/15 to its lowest terms.
Answered by Mike
it would be 2/3

Remember, when you write a fraction is is part/whole. You want to know how many rolls are left so do the subtraction (15 to start with, 10 are used)...this will be your "part" or numerator. The amount you started with will be your "whole" or denominator. You can reduce them by dividing them both by 5.

Yay! You're right! :-)

What is a fraction?

part/whole = fraction

10/15 = fraction

5 into 10 = 2 (our numerator)

5 into 15 = 3 (our denominator)

Final answer: 2/3

Done!
