old denominator --- D
old numerator --- 2D-5
new denomintor D-1
new denom. 2D-5 + 3
so (D-1)/(2D-2) = 5/4
I 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
Oh now I get it. in the last step
your a genius.
This is my work:
-----= -- Cross multiply you get:
2D-2 4 10D-10=4D-4
THE DENOMINATOR IS 4 MORE THAN ITS NUMERATOR.IT IS DECREASED FROM NUMERATOR AND 2 IS ADDED TO THE DENOMINATOR,THE RESULTING FRACTION IS 3/4.FIND THE ORIGINAL FRACTION.
