A famer has 50 sheep and 20 cows.Calculate the fraction of his animals that are cows.

20 cows

70 animals

so, 20/70

There are 50 sheep and 20 cows.

50+20=70
Answer:20/70

in a box of 24 beads, ten are white and eight are red. the rest of the beads are blue . calculate the fraction of the of the beads that are blue.

To find the fraction of the farmer's animals that are cows, we need to divide the number of cows by the total number of animals.

Step 1: Find the number of cows
The problem states that the farmer has 20 cows.

Step 2: Find the total number of animals
The problem states that the farmer has 50 sheep and 20 cows. To find the total number of animals, we add the number of cows and the number of sheep.
Total number of animals = 20 cows + 50 sheep = 70 animals

Step 3: Calculate the fraction of animals that are cows
To calculate the fraction of animals that are cows, divide the number of cows by the total number of animals.
Fraction of animals that are cows = Number of cows / Total number of animals
Fraction of animals that are cows = 20 cows / 70 animals

Step 4: Simplify the fraction
To simplify the fraction, divide both the numerator and denominator by their greatest common divisor (GCD).
In this case, the GCD of 20 and 70 is 10.
Fraction of animals that are cows = (20/10) cows / (70/10) animals
Fraction of animals that are cows = 2/7

Therefore, the fraction of the farmer's animals that are cows is 2/7.
