c. Illustrate and describe the process of decomposing 1 liter of water into 10 smaller units.
Answer:
Explanation:
I decomposed 1liter of water into 10 smaller units by pouring 100 milliliter of water into each cup.Then count each cup by 100ml.I found that 1000ml that is 10 groups of 100ml is equal to 1 liter.
1000ml/10=100ml.
d. Illustrate and describe the process of decomposing Cup K into 10 smaller units.
Answer:
Explanation:
I decomposed 100ml of water into 10 smaller units by pouring 10milliliter of water into each cup.Then count each cup by 10ml.I found that 100ml that is 10 groups of 10ml is equal to 100ml.
100ml/10=10ml
