Here is the explanation and a worksheet to practice “menos” as a way to tell time.
In Spanish we have another way of saying the time by subtracting the minutes remaining to the next hour and saying it, like this:
For 5:55 PM, we say “It’s six minus five.”
Son las seis (6) menos cinco (5).
We usually do this with minute numbers grater than 30.
For 11:35 AM,
Son las doce (12) menos veinticinco (25).
