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

Answer:

$7:\dfrac{1}{3}=21$ pieces

Step-by-step explanation:

Suppose you have a 7 feet long wood.

You need to find how many $\frac{1}{3}$-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:

$7:\dfrac{1}{3}=\dfrac{7}{1}\cdot \dfrac{3}{1}=21$
