1) 8 : 1 1/7 = 8 : 8/7 = 8 * 7/8 = 7 (кг) - во втором ящике;
2) 8 * 1 1/8 = 8 * 9/8 = 9 (кг) - в третьем ящике.
3) 8 + 7 + 9 = 24 (кг) - столько винограда в трёх ящиках.
Ответ: 24 кг.

3. Reading Comprehension: "Was-Were Story"
Last week, there was one really, really bad day. It was Monday. Usually, there are about 25 students in my class, but that day, there were only 5 people! It wasn't warm. In fact, it was really cold. It was raining a lot. It was dark and gray outside. There wasn't any sunshine. I think the students weren't at school because they were sick. They were at home. Maybe they were in bed. Mr. Jibbit is our teacher. He is always at school. He is never at home on a Monday. Last Monday was no different. He was not in bed. He was in the classroom, and he was cold! Why was he so cold? That's a very good question. He was cold because the heater in the school was broken. It was freezing. The school was like a refrigerator. Our room was like a freezer! And poor Mr. Jibbit was like ice! The small class was cold, cold, cold! The next days were much warmer. The heater was fixed on Tuesday, so everything was ok. There were 25 students, not only 5. But where was Mr. Jibbit? He wasn't there. He was at home, sick in bed!
