помогите сложить дроби 2/7+3/14. спамибо

сделать синтаксический разбор предложений:

You stop sending clothes to the laundry, and the laundress catches you in the street and asks you why; you mumble something, and she, thinking you are sending the clothes elsewhere, is your enemy for life. The tobacconist keeps asking why you have cut down your smoking. There are letters you want to answer, and cannot, because stamps are too expensive.
