Это выглядит вот так 9/40+3/4-19/20=9/40+30/40-38/40=39/40-38/40=1/40 Вот и ответ Потому что их надо привести к одинаковым знаменателю а знаменатель будет 40

evaldvakengut: будет ровно 1

Hi, I'm Bella!
We have just moved to another town. Before that we lived in a small flat downtown, but now we live in a very big house. Despite the fact that the town where we live now is not very big, I like it here. There are some parks, a (library/post office/town hall) where you can not only read but also get to know some new people. Also, there is a (stadium/art gallery/estate) which I'm planning to go to next week for a football match and two (cafes/cinemas/shopping centers) which we've already been to. We've watched new cartoons with my brother.

Now we need to do more housework, but it's OK. I always help my mum in the kitchen: when she (does the shopping/does the cooking/does the ironing) I help to clean and cut vegetables; after dinner I usually help to (set the table/dry the dishes/load the dishwasher)it is so convenient now that we don't need to wash the dishes ourselves! My dad (loads the washing machine/washes the dishes/vacuums the floor) on both floors, (but/because/and) my brother is too small to do anything hard: he only (does the housework/vacuums the floor/makes his bed) in his room. (but/Unfortunately/anyway) in spite of having to do more now, we are happy here!
