1) 7 (Я) + 4 (Г) + 5 (С) = 16 частей - всего
2) 160 гр груш (Г) - 
160 : 4 = 40 грамм одна часть 
Яблок: 40 * 7 = 280 грамм
Слив  40 * 5 = 200 грамм 
Всего: 160 + 280 + 200 = 640 грамм
3) 350 грамм яблок
350 : 7 = 50 гр
Груш 4 * 50 = 200 гр
Слив 5 * 50 = 250 гр
Всего: 350 + 200 + 250 = 800 грамм
4) 225 грамм слив
225 : 5 = 45 гр
Яблок 7 * 45 = 315 гр
Слив 5 * 45 = 225 гр
Груш 4 * 45 = 180 гр
Всего 315 + 225 + 180 = 720 гр

Task 1. Read the text about organic food and mark the statements True or False.
Organic Food No More Nutritious
Scientists have revealed that organic and non-organic food
contain pretty much the same amounts and kinds of vitamins and
other nutrients. This might be surprising news for those of us who
choose to buy organic believing it to be healthier. Researchers from
America's Stanford University concluded that there might not be
any extra health benefits to buying organic, thus people might be
better off saving their money and buying
non-organic produce. Lead researcher Dr Crystal Smith-Spangle said there was no difference in the vitamin content in fruit, vegetables, meat and dairy products in organically- and conventionally- produced food. She said the only difference was slightly more phosphorus in the organic products.
Dr Smith-Spangle's review of over 200 different reports on organic food suggests people should perhaps revise their shopping choices, based on the levels of pesticides. Smith Spangler said both organic and conventional foods rarely exceeded the allowable limits for pesticides in the USA. She said the evidence wasn't too clear on whether the difference in pesticides would have an effect on health. She concluded by saying consumers should know there is overwhelming evidence that eating fruit and vegetables is good for your health, so people should eat more fresh produce, whether it is organic or conventional. Organic foods accounted for $31 billion in sales in the USA last year, up from $3.6 billion in 1997.
1. Scientists have found that non-organic food is no longer nutritious.
2. Research says vitamin content in organic/non-organic food is the same. 3. The researcher said people should think more about pesticides.
4. Non-organic food in the U.S. contains pesticides over acceptable limits.
