3/5 of the animals on the farm are cows. The rest are chickens.
There are 18 cows. How many are chickens?
(3/5)x = 18
x = 30 = total animals
The ratio of goats to cows in a farm is 5:3 if there are 20 more goats than cows, how many animals are there in the farm?
To find out how many chickens are on the farm, we first need to find the total number of animals on the farm. We know that 3/5 of the animals are cows, and we also know that there are 18 cows.
Let's denote the total number of animals on the farm as 'x'. We can set up the following equation:
3/5 * x = 18
To solve for x, we can multiply both sides of the equation by (5/3):
(5/3) * (3/5) * x = (5/3) * 18
The (3/5) and (5/3) cancel out, leaving us with:
x = 18 * (5/3)
Simplifying the expression:
x = 30
So, the total number of animals on the farm is 30. Now, to find the number of chickens, we need to subtract the number of cows from the total number of animals:
Number of chickens = Total number of animals - Number of cows
Number of chickens = 30 - 18
Calculating this expression:
Number of chickens = 12
Therefore, there are 12 chickens on the farm.
