We have to count how many times does 4/14 fit inside 68. To do so, we have to perform a division:

[tex]68\div\dfrac{4}{14}[/tex]

But dividing by a fraction is the same as multiplying the inverse of that fraction:

[tex]68\div\dfrac{4}{14}=68\cdot\dfrac{14}{4}[/tex]

So, divide 68 by 4 and then multiply the result by 14 to get the number of pieces you can cut.
