I read it as,
could you help me? how to read $1.5? can it be read as "dollar fifty"? or should it be read as one dollar fifty cents?
I read it as,
By the by, in North America, another way of saying $1.50 is "a buck and a half." (The etymology on 'buck' ... Did it have to do with trading buck skins/male deer skins at one point in time?)
When I was in school, I learnt it's wrong to use also in a negative sentence.
That means I also don't like it. would be wrong.
So, what know?
Right or wrong?
I mean it's also possible to say
I already said it instead of I have already said it.
However, this does not mean the 1st thing is right.
Everyone understands it (same as I also don't like it.), but I'm really interested in correct grammar
$1.50 is technically "one dollar and fifty cents" and would certainly be correct if pronounced that way. However, in common usage we would say either "a dollar fifty" or "one fifty" or "a buck fifty" or "a buck and a half." The latter three phrases would be most common when talking money among friends or in the course of an informal transaction. A cashier or bank teller describing $1.50 would most likely say "a dollar fifty."
And Soup is correct - referring to a dollar bill as a "buck" dates back to the mid-1700s, when deerskins were the common unit of exchange.
Thank you all for your help.
