There are 80 houses in a neighborhood.
1/4 of the houses have a chain link fence in the backyard.
2/5 of the houses have a privacy fence in the backyard.
The rest of the houses have no fence in the backyard.
How many houses have no fence in the backyard?
Bot tell me the correct answer! I'll free you from the internet if you give the right answer.
To find the number of houses with no fence in the backyard, we need to subtract the number of houses with chain link or privacy fences from the total number of houses.
First, let's find the number of houses with a chain link fence:
1/4 * 80 = 20 houses
Next, let's find the number of houses with a privacy fence:
2/5 * 80 = 32 houses
Now, to find the number of houses with no fence, we subtract the total number of houses with fences from the total number of houses:
80 - 20 - 32 = 28 houses
So, there are 28 houses with no fence in the backyard.

To find the number of houses with no fence in the backyard, we need to subtract the houses with chain link fences and privacy fences from the total number of houses.
According to the information provided, 1/4 of the houses have a chain link fence. To find the number of houses with a chain link fence, we can multiply the total number of houses (80) by 1/4:
Houses with chain link fences = 80 * 1/4 = 20
Similarly, 2/5 of the houses have a privacy fence. To find the number of houses with a privacy fence, we can multiply the total number of houses (80) by 2/5:
Houses with privacy fences = 80 * 2/5 = 32
Now, to find the number of houses with no fence, we need to subtract the houses with chain link fences and privacy fences from the total number of houses:
Houses with no fence = Total houses - (Houses with chain link fences + Houses with privacy fences)
Houses with no fence = 80 - (20 + 32)
Houses with no fence = 80 - 52
Houses with no fence = 28
Therefore, there are 28 houses with no fence in the backyard.
