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?

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.

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.

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.
