**Reiny**, Monday, October 27, 2008 at 9:36pmold denominator --- D

old numerator --- 2D-5

new denomintor D-1

new denom. 2D-5 + 3

so (D-1)/(2D-2) = 5/4

solve

- OOPS again math -
**Reiny**, Monday, October 27, 2008 at 9:44pmI seem to be making some silly copying errors tonight

change to :

new denomintor D+3

new numerator 2D-5 - 1

so (2D-6)/(D+3) = 5/4

solve

- OOPS again math -
**amir**, Monday, October 27, 2008 at 9:52pmOh now I get it. in the last step

3D=39

-----

3 3

so D=13

tysm!

your a genius.

**amir**, Monday, October 27, 2008 at 9:47pmThis is my work:

D-1 5

-----= -- Cross multiply you get:

2D-2 4 10D-10=4D-4

-4D -4D

6D-10=-4

+10+10

6D=6

-----

6 6

D=1?

- OOPS again math -
