Question

Accepted Answer

### Question 2:
# Explanation:
## Step1: Recall the conversion factor
We know that 1 gram = 1000 milligrams. So to convert grams to milligrams, we multiply the number of grams by 1000.
## Step2: Perform the conversion
For 6 grams, we do $6\times1000 = 6000$ milligrams.
# Answer:
6000

### Question 3:
# Explanation:
## Step1: Recall the conversion factor
We know that 1 liter = 1000 milliliters. So to convert liters to milliliters, we multiply the number of liters by 1000.
## Step2: Perform the conversion
For 9 liters, we do $9\times1000 = 9000$ milliliters.
# Answer:
9000

### Question 7:
# Explanation:
## Step1: Recall the conversion factor
We know that 1 kilogram = 1000 grams. So to convert kilograms to grams, we multiply the number of kilograms by 1000.
## Step2: Perform the conversion
For 5 kilograms, we do $5\times1000 = 5000$ grams.
# Answer:
5000

### Question 8:
# Explanation:
## Step1: Recall the conversion factor
We know that 1 liter = 1000 milliliters. So to convert liters to milliliters, we multiply the number of liters by 1000.
## Step2: Perform the conversion
For 2 liters, we do $2\times1000 = 2000$ milliliters.
# Answer:
2000

### Question 9:
# Explanation:
## Step1: Recall the conversion factor
We know that 1 gram = 1000 milligrams. So to convert grams to milligrams, we multiply the number of grams by 1000.
## Step2: Perform the conversion
For 4 grams, we do $4\times1000 = 4000$ milligrams.
# Answer:
4000

### Question 10:
# Explanation:
## Step1: Recall the conversion factor
We know that 1 kilogram = 1000 grams. So to convert kilograms to grams, we multiply the number of kilograms by 1000.
## Step2: Perform the conversion
For 9 kilograms, we do $9\times1000 = 9000$ grams.
# Answer:
9000

### Question 1 (Do You Understand?):
# Brief Explanations:
To measure mass (of a person), the metric unit "kilogram" is commonly used because a person's mass is typically in the range where kilograms are practical (e.g., a child might be 20 kilograms, an adult 60 - 100 kilograms). For the amount of blood in the body, the metric unit "liter" is used. The average adult has about 5 - 6 liters of blood, and liters are suitable for measuring volumes of liquids like blood in the body.
# Answer:
To measure your mass, the metric unit "kilogram" is used (as a person's mass is typically in the kilogram range). To measure the amount of blood in your body, the metric unit "liter" is used (since blood is a liquid and the volume of blood in the body is typically measured in liters, with an average adult having 5 - 6 liters of blood).

### Question 4 (Independent Practice):
# Brief Explanations:
Medicine in a pill is a very small amount of mass. The metric unit "milligram" is appropriate because pills usually contain small quantities of active ingredients (e.g., a pill might have 500 milligrams of a drug), and milligrams are used for measuring small masses.
# Answer:
The metric unit to measure medicine in a pill is "milligram" (because the mass of medicine in a pill is very small, and milligrams are used for measuring small masses).

### Question 5 (Independent Practice):
# Brief Explanations:
Ink in a pen is a small volume of liquid. The metric unit "milliliter" is suitable because the amount of ink in a pen is relatively small (e.g., a pen might hold 1 - 5 milliliters of ink), and milliliters are used for measuring small volumes of liquids.
# Answer:
The metric unit to measure ink in a pen is "milliliter" (because ink in a pen is a small volume of liquid, and milliliters are used for measuring small volumes of liquids).

### Question 6 (Independent Practice):
# Brief Explanations:
The mass of a pencil is relatively small. The metric unit "gram" is appropriate because a pencil typically has a mass of a few grams (e.g., a wooden pencil might have a mass of around 5 - 10 grams), and grams are used for measuring small to moderate masses.
# Answer:
The metric unit to measure the mass of a pencil is "gram" (because the mass of a pencil is relatively small, and grams are used for measuring small to moderate masses).
