Elementary school mathematics chasing application problems
1. There is a batch of apples in the shop. It sold 2/9 kilograms on the first day. The next day, I sold the remaining 7 days of 1. On the third day, 1 for the remaining six days was sold. There are still 30 kilograms left at this time. How many kilograms of apples are there in this shop?

2. Some people read a book. On the first day, they read more than 2/7 of the total pages, and on the second day, they read the remaining 2/3, lacking 10 pages. There are still 62 pages left to read. How many pages are there in this book?

There are 65,438+080 apples in three baskets. If you put 65,438+0 apples in the second basket into the first basket and 65,438+0 apples in the third basket into the second basket, the number of apples in the three baskets is the same. How many apples are there in each basket?

1. There are still 7/9 on the first day, 6/9 on the second day, that is, 2/3=4/6, and on the third day 1 minus 4/6 times 1/6 equals 5/9. That's 30 kilograms. The original apple in the shop was 30 divided by 5/9=54 kg.

2. Rewind the tape from the back quickly. 62- 10 = 52 pages, that is, after reading the remaining two thirds and 1 the next day, it is 52 pages. So there were 52*3= 156 pages before reading the next day. On the first day, seven-fifths of two-sevenths should be 156.

As many apples, there are 180/3=60 apples in each basket.

Start with the third basket of apples. If you take away 1, there are still 3/4 apples. There are 60 apples at this time, so the original 60 is divided by 3/4, and you get 80 apples. If you take out 65,438+0 and 2/3 apples in the second basket, you get 60 apples. Then the first basket has 65,438+080-60.
