The current price of Andersen's fairy tales is 1 / 6 lower than the original price. The original price is 4 yuan higher than the current price. How much is the original price?

Original price = 4 △ 1 / 6 = 24 yuan

There is a question in my son's daily series, which is like this: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 +1000＝?

1+1000=1001 1001x500=500500

4 divided by (y + 2) minus 6 divided by (2Y minus 1) equals 1. What is y equal to?

Remove the denominator to get 4 (2y-1) - 6 (y + 2) = (2y-1) (y + 2)
The result is 2Y ^ 2 + y + 14 = 0
Because the discriminant is less than 0
So this equation has no solution
Therefore, the original formula has no solution

Whether 2100 is a leap year or not
2100 / 400 is not divisible, but 2100-4 = 20962096 / 4 = 524. Income and output are leap years. It should be leap years after four years. According to the teacher, the whole hundred years must be divided by 400. Why?

The simple calculation method of the leap year of the Gregorian calendar: (a year that meets one of the following conditions is a leap year) 1. It can be divisible by 4, but not by 100. (for example, 2004 is a leap year, 1900 is not). 2. It can be divisible by 400. (for example, 2000 is a leap year). You can read it. 2100 can be divisible by 4, but also by 100, If you don't meet the condition 1, 2100 can't be divided by 400, and you don't meet the condition 2, so 2100 is not a leap year

Xiaogang plans to finish reading a 120 page story book in one week (seven days). On the first day, he reads 15 pages of the book, and the rest 16 pages a day. Can he finish it in the original time?

120 × (1-15) △ 16 = 120 × 45 △ 16, = 6 (days). 6 + 1 = 7 (days). A: it takes him seven days to finish the book, so he can finish it within the prescribed time

Cut a cuboid 10 cm in length, 8 cm in width and 6 cm in height into two cuboids of the same shape and size. What is the maximum and minimum surface area of the two cuboids?

The surface area of the original cuboid is 2 × (10 × 8 + 10 × 6 + 8 × 6) = 376 CM & # 178;
The maximum sum of the surface area of the two cuboids is = 376 + 2 × 10 × 8 = 536 CM & # 178;
The minimum sum of the surface area of the two cuboids is = 376 + 2 × 6 × 8 = 472 CM & # 178;
