how knowing the number of pennies in one jar can help you estimate the number of pennies in a second jar that is four times as large. give me an example.

4500 pennies are in a pint...how many are in a half gallon (4pints).

ans: 4*4500

If there are 100 pennies in one jar, there must be about 400 pennies in a jar that is four times as large.

Do you see how I got 400?

To estimate the number of pennies in a second jar that is four times as large as the first jar, we can use a simple proportion.

Let's assume there are 100 pennies in the first jar. Since the second jar is four times larger, we can multiply the number of pennies in the first jar (100) by 4, which gives us 400 pennies.

So, if we know that there are 100 pennies in the first jar, we can estimate that there would be around 400 pennies in the second jar.

Knowing the number of pennies in one jar can help you estimate the number of pennies in a second jar that is four times as large by using proportions.

Here's an example to illustrate this:

Let's say there are 100 pennies in the first jar. We want to estimate the number of pennies in the second jar.

Step 1: Determine the size difference between the two jars
Since the second jar is four times as large as the first jar, we can say that the ratio of the second jar's size to the first jar's size is 4:1.

Step 2: Set up the proportion
To estimate the number of pennies in the second jar, we will set up a proportion using the size ratio and the number of pennies:

(4:1) = (x:100)

The 'x' represents the number of pennies in the second jar, and 100 is the number of pennies in the first jar.

Step 3: Solve the proportion
To solve the proportion, we can cross-multiply and then divide:

4 * 100 = 1 * x

400 = x

Based on this estimation, we can estimate that there are 400 pennies in the second jar.

It's important to note that this is just an estimate and may not be exact, but it gives us a reasonable approximation based on the known information.
