Bid/Ask Notations

Can someone explain the different notations that the exam exhibits bid-ask spreads? I understand the normal (ex. 1.0000-1.1000) but I get caught up when it is listed at 1.000/10 or 1.0000-10…

Last week before the exam! Hope everyone is crunching it out. Confidence is key

In the last two notations, the second part tells you which digits change from the bid to the ask. They’re equivalent to 1.000/1.010 and 1.0000/1.0010, respectively: only the last two digits are changing.
