1 dollar = 100 cents = 10 cents * 10 cents = 1/10 dollar * 1/10 dollar = 1/100 dollar = 1 cent
Here is the proof that 1 dollar = 1 cent. Is there an error in my calculations?
1 dollar = 100 cents = 10 cents * 10 cents =
1/10 dollar * 1/10 dollar = 1/100 dollar = 1 cent
it's really 1/10 * 100 = 10. 10 * 10 = 100, which is 100 cents or 1 dollar.
