You've baked 26 cookies, which is two-thirds of all the cookies you planned to bake. How many cookies did you plan to make?
hodyreva [135]

Answer,

<em>(26/2) * 3</em>

<em>= 39</em>

Explanation,

<u><em>26 cookies is only 2/3 of 3/3. So, we divide 26 by 2 to see how many cookies are in 1/3. We then can find out that when you make 1/3 of the cookies there are 13. Since that is only 1/3 and we want to find out 3/3. We multiply 13 by 3 and get 39 which is all the cookies she planned to make.</em></u>


<u><em>Hope this helps :-)</em></u>
