Hello!

ANSWER:

Ms. Stapleton had 1,040 ducks on her farm.



EXPLANATION:

What we know:

We know that altogether Ms. Stapleton had 2,600 animals.

35% of which were hens, 25% were goats, and the rest were goats.



How to solve:

To find out how many of the animals are ducks, we must first find out how many are hens and ducks and then subtract them from the total number of animals.



Convert the percentages to decimals by dividing them by 100, then multiply.

35 ÷ 100 = 0.35

25 ÷ 100 = 0.25

2,600 × 0.35 = 910

2,600 × 0.25 = 650

910 + 650 = 1,560


Ms. Stapleton had 910 hens and 650 goats on her farm, altogether 1,560. We must subtract:

2,600 - 1,560 = 1,040
