Question

В первый день туристы прошли 1 1/5 а на следущий день они прошли на 4 2/5 больше ч а в третий день они прошли 7 4/5 км меньше чем в первые два дня

Answer 1

1 день- 1 1/5 км
2 день- на 4 2/5 >, чем в 1 день
3 день- на 7 4/5 км <, чем в 1 и во 2 дни вместе
1) 1 1/5 +4 2/5= 5 3/5(км)- во 2 день
2) 7 4/5 +(1 1/5 +5 3/5)= 7 4/5+6 4/5=13 8/5= 14 3/5(км)- в 3 день
3) 1 1/5+ 5 3/5+ 14 3/5=20 7/5= 21 2/5(км)
Ответ: всего туристы прошли 21 2/5 км

Answer 2

Problem Analysis

The problem states that on the first day, tourists walked 1 1/5 km. On the next day, they walked 4 2/5 km more than the previous day. On the third day, they walked 7 4/5 km less than the total distance covered in the first two days. We need to find the total distance covered in the three days.

Solution

To find the total distance covered in the three days, we need to add up the distances covered on each day.

Let's calculate the distance covered on each day step by step:

1. On the first day, the tourists walked 1 1/5 km. 2. On the second day, they walked 4 2/5 km more than the previous day. So, we need to add 4 2/5 km to the distance covered on the first day. 3. On the third day, they walked 7 4/5 km less than the total distance covered in the first two days. So, we need to subtract 7 4/5 km from the sum of the distances covered on the first two days.

Let's perform the calculations:

1. Distance covered on the first day: 1 1/5 km. 2. Distance covered on the second day: 1 1/5 km + 4 2/5 km = 5 3/5 km. 3. Distance covered on the third day: (1 1/5 km + 5 3/5 km) - 7 4/5 km.

To simplify the calculations, let's convert all the fractions to a common denominator:

1. Distance covered on the first day: 6/5 km. 2. Distance covered on the second day: 34/5 km. 3. Distance covered on the third day: (6/5 km + 34/5 km) - 39/5 km.

Now, let's perform the calculations:

1. Distance covered on the first day: 6/5 km = 1.2 km. 2. Distance covered on the second day: 34/5 km = 6.8 km. 3. Distance covered on the third day: (6/5 km + 34/5 km) - 39/5 km = 1.2 km + 6.8 km - 7.8 km = 0.2 km.

Therefore, the total distance covered in the three days is 1.2 km + 6.8 km + 0.2 km = 8.2 km.

Answer: The tourists covered a total distance of 8.2 km in the first three days.
