Cos'è un quarto di dollaro, un decino, un nichelino e un penny? Quali sono le loro differenze?

Ci può essere un po' di confusione con nomi come dime, nickel e penny/cent o vedendo le immagini su un lato della moneta, ma non avrete problemi ad usarli in pratica dato che un lato ha dettagli in centesimi chiaramente.

Di seguito vi aiuterà a ricordare i nomi ed eventualmente ad identificarli dalle immagini.

Alcuni esempi che conosciamo per ricordare meglio:

• Se tagliamo la pizza in 2 pezzi, ognuno si chiama metà (1/2 o 50%)
  • similmente, un'ora è 60 minuti, mezz'ora è 30 minuti.
• Se tagliamo la pizza in 4 pezzi, ognuno si chiama un quarto (1/4 o 25%)
  • similmente, un quarto d'ora (60 minuti), cioè 15 minuti.
• I numeri che scriviamo sono in notazione decimale (come 1, 2, 5, 10, 20, 50, 100, ecc), questi decimali sono detti di base-10, yes it is 10 (10% is 10)
  • the binary is of base-2
  • decimal is of base-10
• Like gold, there is a metal called nickel
  • Can the value of a small nickel piece be 5 cents/pennies?
    • because the penny is pretty small

Coins are:

• 1 dollar is
  • 100 cents - a full dollar, so 100%, so 100 cents
  • the coin has one dollar written on one side, some times as “$1”.
• 1 half dollar is
  • 50 cents - 1/2 th of a dollar, so 50%, so 50 cents
  • the coin has a half dollar written on one side.
• 1 quarter dollar is
  • 25 cents - 1/4 th of a dollar, so 25%, so 25 cents
  • the coin has a quarter dollar written on one side.
• 1 dime is
  • 10 cents - 1/10 th of a dollar, so 10%, so 10 cents -- dime starts with d, also decimal starts with which is base-10.
  • the coin has one dime written on one side.
• 1 nickel is
  • 5 cents - made of nickel alloy, 1 cent/penny (below) is not made of nickel possibly as it costs more than 1 cent, so it starts with 5 cents
  • the coin has five cents written on one side.
• 1 penny is
  • 1 cent - a penny is an informal name for a cent in US
  • the coin has one cent written on one side.
• Now, don’t remember more details, as we can derive them
  • what is nickel (5 cents) + nickel (5 cents) is
    • 1 dime (10 cents)
    • so, 2 nickels is 1 dime
    • but, we can always derive this, if we remember the above.

To complete it, the notes are:

• 1, 2, 5, 10, 20, 50, 100 notes

Hope that helped to remember.
