Question

Ten same-sized marbles have a mass of 45.6 grams. What is the
mass of one marble?

Answer 1

Mass per/unit: 4.56

Divide 45.6 by ten(Long division)

`Borrow\:0.60\\= 45\\10 * 4\\= 40\\= 45 - 40\\= 5\\Rewrite\:0.60\:as\:6\quad\:Alternative:Drop\:6\\= 6\\5 < -- > 6 = 56\\10 * 5\\= 50\\= 56 - 50\\= 6\\Drop\:0.0\\= 60\\10 * 6\\60\\= 60 - 60\\= 0\\= 4.56,Remainder\:0`

Hope this helps! Have a good day. :)
