Answer 1

Jawaban:

there are 525 ducks on Holly's farm

Penjelasan dengan langkah-langkah:

To find the number of ducks on the farm, we need to subtract the number of goats and chickens from the total number of animals.

Let's start by finding the number of goats. We know that 20% of the animals are goats, so we can calculate it as follows:

Number of goats = 20% of total animals = 20/100 * 1500 = 300 goats

Next, let's find the number of chickens. We know that 45% of the animals are chickens, so we can calculate it as follows:

Number of chickens = 45% of total animals = 45/100 * 1500 = 675 chickens

Now, to find the number of ducks, we subtract the number of goats and chickens from the total number of animals:

Number of ducks = Total animals - (Number of goats + Number of chickens)

= 1500 - (300 + 675)

= 1500 - 975

= 525 ducks

Therefore, there are 525 ducks on Holly's farm.
