Answer:
1) Part A)
Liters Mililiters
1 1,000
5 5,000
8 8,000
14 14,000
2) Part B)
One way to convert 4.2 liters to milliliters is to <u> multiply </u> the number of liters by the number of milliliters in 1 liter. This means there are <u> 4,200 </u>milliliters in 4.2 liters. The cafeteria has the greatest amount of <u> orange </u>juice, the second greatest amount of <u> grape </u> juice, and the least amount of <u> cranberry </u>juice.
Explanation:
<u>1) Data:</u>
- Grape juice: 8,000 mililiters
- Cranberry juice: 4.2 liter
- Orange juice: 12,000 mililiters
- There are 1,000 mililiers in 1 liter
<u>2) Part A:</u>
<u>Table:</u>
The table is garbled. This is what the tables could look like:
Liters Mililiters
1 1,000
5 5,000
8 8,000
14 14,000
You can see that the table shows a direct relationship between the number of mililiters and the number of liters:
- 1,000/1 = 1,000
- 5,000/5 = 1,000
- 8,000/8 = 1,000
- number of mililiters / liters = 1,000
<u>3) Part B)</u>
Fill in the blanks to explain how Landon can convert 4.2 liters of cranberry juice to mililiters so he can compare the amounts of the different juices:
i) One way to convert 4.2 liters to milliliters is to <u> multiply </u> the number of
liters by the number of milliliters in 1 liter.
- As demonstrated above there is a direct relationship between the number of mililiters and the number on liters, then you must multiply the number of liters by the proportionality constant to find the number of mililiters.
ii) This means there are <u> 4,200 </u>milliliters in 4.2 liters.
- That is the product 4.2 × 1,000 = 4,200.
iii) The cafeteria has the greatest amount of <u> orange </u>juice, the second greatest amount of <u> grape </u> juice, and the least amount of <u> cranberry </u>juice.
Rank the amounts:

Answer: 3.11637
Explanation: The hundred thousandths place is in the fifth place after the decimal. To avoid remembering this, you can simply note that the first place after the decimal is the tenths. You simply keep progressing as you would in whole numbers.
For example 10 becomes 100 when a zero is added. This zero is always added right beside the first zero and indicates the hundreds place.
Furthermore, the general rule for rounding is if the number after the preferred rounding place is 4 or less, the number remains the same. 5 or more means it goes up by one digit.
The answer is 28 for the volume
