Final answer:
There are 0.2 times as many cows as there are goats on the farm, as derived from the ratio of goats to cows which is simplified to 5:1.
Step-by-step explanation:
The problem states that there are 10 goats for every 2 cows on a farm. To find out how many times as many cows as there are goats, we need to set up a ratio. The ratio of goats to cows is 10:2, which can be simplified to 5:1. This means for every 5 goats, there is 1 cow.
Therefore, there are 1/5 times as many cows as goats. To express this as a decimal, we divide 1 by 5:
1 ÷ 5 = 0.2
So, there are 0.2 times as many cows as there are goats on the farm.
