I want to find a website that helps me with grammar usage, 'cause I'm gonna need a lot of help on using the right prepositions and phrasal verbs, eg: to reduce inflation by 15% to 20% this year ... Is it correct? It could be a really advanced and detailed dictionary :D
You will find thousands of phrasal verbs here:
English Phrasal Verbs - UsingEnglish.com
Cambridge Dictionary Online: Free English Dictionary and Thesaurus - Cambridge University Press - Cambridge Dictionaries Online - Cambridge University Press
You sentence is correct, assuming THE RATE inflation currently is 35%.
Thanks a lot![]()
