Apipe is 30 feet long. it needs to be cut into pieces that are 2/3 feet long. how many pieces can be made from this pipe

When it says that it needs to be cut, it means to divide. therefore, you divide the 30 foot pipe by 2/3. Dividing by 2/3 is the same as multiplying by 3/2. 30*30/2 would be the equation. Then you multiply 30 by 30. 90. Then you divide 90 by 2, which is 45.

3cm and 6 and 9 cm that a possibility of that question
