Test Preparation

<p>i know this question might be easy... but i can't seem to get the right answer...
Help me people...
its In the blue book by the college board... pg 475 number 15.. (math section)
I can't draw the picture but hopefully you guys have the book for reference?</p>

<p>the question is: :)
In triangle PQR above, QS/QV=1/3 and PT/PR=3/4. What is the value of the fraction area PST/PQR?
And I am sorry there isn't a picture but the triangle PST is in the triangle PQR, and thier heights are aligned with each other and perpendicular to the base... PLZZZZZ someone help me!</p>

<p>Sorry about the earlier post -- i accidently answered #13 for you instead of #15 (and i was astonished that anyone had difficulty with 13:-P)</p>

<p>This is what i did</p>

<p>Let PT = 3y
Let TR = y</p>

<p>(follows logically from givens)</p>

<p>Let QS = x
Let SV = 2x</p>

<p>(also follows logically from the givens)</p>

<p>The area of the big thing is .5(4y)(3x) = 6xy
The area of the small thing is .5(3y)(2x) = 3xy</p>

<p>The big part is twice as big. The fraction is 1/2.</p>

<p>QED.</p>
