Question

The length of a ribbon is 3/4 meter. Sun yi needs pieces measuring 1/3 meter for an art project. What is the greatest number of pieces measuring 1/3 meter that can be cut from the ribbon. How much will be left

Answer 1

Find the LCD of 3/4 and 1/3, which is 12. Convert 3/4 and 1/3 to twelfths.

3/4 is now 9/12 and 1/3 is now 4/12. 4/12 goes into 9/12 two times, and 1/12 is left.

So, your answer is two pieces can be cut from the ribbon, and 1/12 will be left.
