Question 1209050
.
Frank spent 1/7 of his money on shoes and 2/5 of the remaining amount on a shirt. 
How much money does he have left in terms of a fraction of the original amount?
~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Frank spent  

    {{{1/7}}} + {{{(2/5)*(6/7)}}} = {{{1/7}}} + {{{12/35}}} = {{{5/35}}} + {{{12/35}}} = {{{17/35}}}  of the original amount.


The fraction of money left is  

    {{{1}}} - {{{17/35}}} = {{{35/35}}} - {{{17/35}}} = {{{(35-17)/35}}} = {{{18/35}}}  of the original amount.    <U>ANSWER</U>

Solved.


-------------------


This problem is to solve it in one or two minutes, making standard transformations/calculations with fractions.


Its only goal is to give a student an opportunity to play/(to practice) with fractions.


All other explanations, including making plots and illustrations (as the other tutor does), 
only DISTRACT from the true goal of this exercise.
