Question

You have a pitcher that holds 39.3 oz of lemonade. If each glass holds 8.8 oz, how many glasses can you completely fill?

Answer 1

4 glasses

Explanation:

divide 39.3 and 8.8

`39.3/8.8` = `4.4659` oz

however, the question requires the glasses to completely be filled and so with these types of questions, you must round down to four glasses of lemonade.

Answer 2

`4`

Explanation:

This problem can be modeled by the equation
`8.8x=39.3`, where `x` is the number of glasses that can be filled.
`8.8x=39.3` Divide by `8.8` to isolate `x`
`x=4.465...`

Because each glass must be "completely fill"ed, the partial glass (`0.465...`) cannot be counted, so you can completely fill `4` glasses.

Answer 3

`4` glasses can be filled.

Explanation:

To solve this problem, you want to divide your `39.3` ounces of lemonade by the amount of space in the glasses, `8.8` ounces. To divide with decimals, you want to set it up like this:

In our case, the dividend would be `39.3` and the divisor would be `8.8`. When your divisor is a decimal, in which in our case it is, you have to move all of the decimals over until you can get a whole number in the divisor. Our divisor, `8.8`, is a decimal. If we move the decimal one point to the right, then the number becomes `88`, which is a whole number. Since we moved our decimal point in `8.8`, we also have to move the decimal one space over in `39.3` and get the number `393`.

You would move both decimal points the same number of spaces, so if you had `4.89` divided by `6.7`, you would move both points one spot to the right. It is okay if your divisor is a decimal!

Now that our divisor is a whole number, we can divide. Our new problem is `393` divided by `88`. If we take `88` times `4`, we can get `352`, which as close to `393` as we can get.

So, we would be able to fill up `4` cups of lemonade and still have some left over.
