Question

Which equation calculates the number of 1/3-foot pieces that can be cut from a piece of

wood that is 7 feet long?

Answer 1

`7:(1)/(3)=21` pieces

Explanation:

Suppose you have a 7 feet long wood.

You need to find how many
`(1)/(3)`-foot pieces can be cut from this wood.

To find this number of pieces, you have to divide the whole length of the wood by the length of one piece:

`7:(1)/(3)=(7)/(1)\cdot (3)/(1)=21`
