Question

Joseph has 150 animals on his farm. ⅕ of the animals are chickens, ⅕ of the animals are cows, and the rest of the animals are goats. How many goats does Joseph have on his farm?

Answer 1

Answer:

90 goats

Step-by-step explanation:

Number of chickens in  farm = (1/5) of 150

                                               = $\frac{1}{5}*150$

                                               = 1 * 30

                                               = 30

Number of cows in  farm = $\frac{1}{5}*150$

                                         = 1 * 30

                                         = 30

Number of goats in  farm  = 150 - (30 + 30)

                                           = 150 - 60

                                           =  90

Answer 2

Answer:

Joseph have 90 goats on his farm

Step-by-step explanation:

To solve this problem we first have to subtract the fraction of chickens and cows from 1  to find the fraction that represents goats

(1 - ⅕) - ⅕ = 3/5

Now that we know the fraction of goats we multiply it by the total number of animals

3/5 * 150 = 90

Joseph have 90 goats on his farm
