Question

Туристы проехали 1/5 всего пути на поезде , 1/4 пути-на автобусе, а остальную часть пути проплыли на катере. Какую часть пути туристы проплыли на катере? Запишите десятичной дробью части пути в порядку убывания.

Answer 1

1/5+1/4=5/20+4/20=9/20
1-9/20=11/20 проплыли на катере

Answer 2

Problem Analysis

The problem states that tourists traveled 1/5 of the total distance by train, 1/4 of the distance by bus, and the remaining part of the journey by boat. We need to determine the fraction of the distance traveled by boat.

Solution

To solve this problem, we can use the concept of finding the fraction of a whole. Since the tourists traveled 1/5 of the distance by train and 1/4 of the distance by bus, the fraction of the distance traveled by boat can be calculated as follows:

1 - (1/5) - (1/4)

Let's calculate this:

1 - (1/5) - (1/4) = (20/20) - (4/20) - (5/20) = 11/20

Therefore, the tourists traveled 11/20 of the total distance by boat.

Answer

The tourists traveled 11/20 of the total distance by boat.
