Final answer:
To find the number of goats, use the ratio of sheep to goats and set up a proportion.
Step-by-step explanation:
To find the number of goats, we need to use the ratio of sheep to goats. The ratio is 7:2, which means for every 7 sheep, there are 2 goats. We know that there are 28 sheep, so we can set up a proportion:
(number of sheep) / (number of goats) = (sheep ratio) / (goat ratio)
Substituting the given values:
28 / x = 7 / 2
Cross-multiplying:
2 * 28 = 7 * x
Simplifying:
56 = 7x
Dividing both sides by 7:
x = 8
Therefore, there are 8 goats.
