Question 1.
Emma also has a button and her math book in her backpack. Use these objects to describe the relative sizes of milligrams, grams, and kilograms.
A. Which object is heavier?
Answer:
Math book is heavier.
B. The button has a mass of 1 gram. The math book has a mass of 1 kilogram. Which unit ¡s greater, a gram or a kilogram?
Answer:
Kilogram is greater than gram.
C. There are 1,000 grams in 1 kilogram. How many buttons would it take to equal the mass of the math book?

Question 1.
An eraser has a mass of 4 grams. How does the mass of the eraser compare to a token with a mass of 4,000 milligrams? Explain how you know your answer is correct.
Answer:
An eraser has a mass of 4 grams.
We know that 1 gram is equal to 1,000 milligrams.
To convert 4 grams into milligrams we need to multiply 4 with 1,000 the product is equal to 4,000 milligrams.
4 gm = 4 x 1,000 = 4,000 mg
So, the mass of the eraser is equal to the token with a mass of 4,000 milligrams.
Compare. Use >, <, or =.
Question 2.
5 liters 500 milliliters
Answer:
5 liters 
500 milliliters
Explanation:

Question 7.
Answer:
Explanation:
1 kilogram is equal to 1,000 grams.
1 kg = 1,000 gm
? kg = 2,000 gm
(2,000 x 1)/1,000 = 2 kg
So, 2 kg is equal to 2,000 grams
1 kg = 1,000 gm
7 kg = ? gm
(1,000 x 7)/ 1 = 7,000 gm

Answer:
Explanation
1 gram is equal to 1,000 milligrams.
1 gm = 1,000 mg
3 gm = ? mg
(1,000 x 3)/ 1 = 3,000 mg
So, 3 grams is equal to 3,000 milligrams.
1 gm = 1,000 mg
? gm = 5,000 mg
(5,000 x 1)/1,000 = 5 gm
So, 5 grams is equal to 5,000 milligrams
Question 9.
Answer:
Explanation:
1 liter is equal to 1,000 milliliters.
1 liter = 1,000 milliliters

Question 14.
STEM Zachary fills beakers with a solution for testing chemicals. Two beakers hold 350 milliliters each, two beakers hold 400 milliliters each, and one beaker holds 500 milliliters. Zachary claims he has 2 liters of solution to use for testing. Is he correct? Explain your answer.
Answer:
Yes, Zachary is correct, because he has 2 liters of solution to use for testing.
Explanation:
Zachary fills beakers with a solution for testing chemicals. Two beakers hold 350 milliliters each.
350 + 350 = 700 ml
Two beakers hold 400 milliliters each.
