Question

a pipe 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

Answer 1

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.
