[Tommy-Jane]

1.Your task is twice easier than mine.
2.Your task is two times easier than mine.

The first one seems incorrect to me. Am I right?

2.Your task is two times easier than mine.

They are both wrong. Any phrase of the type "A is twice as easy/light/cheap/short/ as B" is meaningless unless the index unit is given, ie. twice what?
"A is twice as hard/heavy/expensive/tall as B" does make sense because it means twice the difficulty/weight/price/height of B.

For example, if B weighs 4kg. and A is two times lighter (ie. 8kg lighter), A weighs -4kg.
