В and На

[dezelina.livejournal.com]

Hi everyone,

Can someone tell me when to use в and when to use на when trying to express changes in quantity.  For example, production rose by 20%, the amount decreased by 20%?  I have seen в and на used after verbs like these, and never know which preposition is correct.

Thanks in advance!

Easy: в ... раз(а), but на ... процента(процентов).

«В» with «раз», «на» otherwise.

Preposition "в" means multiplication, "на" means increase, addition.

yep, as well as division and subtraction.

в - multiplication and division.
увеличилось в Х раз
уменьшилось в Х раз

на - addition and subtraction
увеличилось на Х единиц/процентов
уменьшилось на X единиц/процентов

exactly, "в два раза больше" = "*2" but "на десять больше" = "+10"
