Question

даю 15 пунктов за лучшее решение!Решите с объяснением Туристам необходимо пройти 33 км .В первый день они прошли 10(целых) 7\25 км,во второй- 12 9\25 . Сколько километров им осталось пройти?

Answer 1

1) узнаем сколько они прошли

10 7\25 + 12 9\25 = 22  16\25

2) теперь узнаем сколько ему осталось пройти

33 - 22 16\25 = 32 25\25 - 22 16\25 = 10 9\25 или 10,36км

ответ им осталось пройти 10.36км

Answer 2

33-10 7\25= 22 18\25

22   18\25 - 12 9\25 = 10          9\25 

Ответ: 10(целых) девять  двадцать пятых км

 

 

 

 

 

Answer 3

Problem Analysis

The problem states that a group of tourists needs to cover a distance of 33 km. On the first day, they covered 10 7/25 km, and on the second day, they covered 12 9/25 km. We need to calculate how many kilometers they have left to cover.

Solution

To find the total distance covered by the tourists, we need to add the distances covered on the first and second days. Then, we can subtract this total distance from the total distance of 33 km to find the remaining distance.

Let's calculate the total distance covered on the first day: - Distance covered on the first day = 10 7/25 km

Next, let's calculate the total distance covered on the second day: - Distance covered on the second day = 12 9/25 km

To find the total distance covered, we add the distances covered on the first and second days: - Total distance covered = Distance covered on the first day + Distance covered on the second day

Finally, we subtract the total distance covered from the total distance of 33 km to find the remaining distance: - Remaining distance = Total distance - Total distance covered

Let's calculate the remaining distance:

Step 1: Convert the mixed fractions to improper fractions: - Distance covered on the first day = 10 7/25 km = (10 * 25 + 7) / 25 km = 257/25 km - Distance covered on the second day = 12 9/25 km = (12 * 25 + 9) / 25 km = 309/25 km

Step 2: Calculate the total distance covered: - Total distance covered = (257/25) km + (309/25) km = (257 + 309) / 25 km = 566/25 km

Step 3: Calculate the remaining distance: - Remaining distance = 33 km - (566/25) km

To simplify the calculation, we can convert 33 km to a fraction with a denominator of 25: - 33 km = (33 * 25) / 25 km = 825/25 km

Now, we can calculate the remaining distance: - Remaining distance = (825/25) km - (566/25) km = (825 - 566) / 25 km = 259/25 km

Therefore, the tourists have 259/25 km left to cover.

Answer

The tourists have 259/25 km left to cover.
