Math CentralQuandaries & Queries


i have confused my brain and its driving me crazy i am trying to write 1.2 as a fraction but each time i do it i come out with a different number please please help


Think of it in terms of money. $1.20 is one dollar and twenty cents. If you lived in a country that had a twenty cent coin then this coin would be one fifth of a dollar. Thus $1.20 would be six twenty cent coins, that is six coins each of which is worth one fifth of a dollar, or six fifths of a dollar. Hence

1.2 = 6/5

I hope this helps,
