Question

If a piece of land has enough grass to feed 15 cows, how long will it last for 2 cows?

Answer 1

To find out how long the grass will last for 2 cows, set up a proportion using the number of cows and the amount of grass available. Solve the proportion by cross-multiplying and then dividing to find the time.

Step-by-step explanation:

To find out how long the grass will last for 2 cows, we can set up a proportion using the number of cows and the amount of grass available. The proportion can be written as:

15 cows : grass available = 2 cows : x (how long it will last)

We can solve this proportion by cross-multiplying:

15 * x = 2 * grass available

Now, we can divide both sides of the equation by 15 to solve for x:

x = (2 * grass available) / 15

So, the grass will last for (2 * grass available) / 15 units of time for 2 cows.
