Question

Of the 46 cities seven have a lake and 20 want to have a river running through them what fraction of these 46 cities have a lake or river running through them

Answer 1

Answer: The fraction of these 46 cities that have a lake or river running through them is 7/46.

Explanation:

Hi, to solve this problem we have to analyze the information given:

• Number of cities: 46
• Cities that have a lake: 7
• Cities that want to have a river: 20

The cities that have a lake or river running through them are 7 (the 20 that only want it don´t count).

So, we have to divide the number of cities that have a lake or river running through them (7) by the total number of cities (46).

Mathematically speaking:

7/46

The fraction of these 46 cities that have a lake or river running through them is 7/46.
