3a-6/4a^2 times 2a/5a-10?

Question may be read a number of different way due to lack of brackets.
Will take a GUESS at :-

[ (3a - 6) / 4a² ] [ 2a / (5a - 10) ]

3(a - 2) (2a)
--------------------
(4a²) (5) (a - 2)

6a
--------
20a²

3
------
10 a

(3a - 6)/4a^2 * 2a/(5a - 10)
= 3(a - 2)/2(2a^2) * 2/5(a - 2) (cancel out a - 2 , 2)
= 3/2a^2 * 1/5
= 3/10a^2
