son las vs es la

Question

what is the difference between son las and es la in short when do we use this both and how we write 100 in spanish

Answer 1

Es la 1:00 de la tarde Es la 1:00 de la mañana.

These are the two instances in which telling time is done in the singular.

The rest is done in the plural:

Son las 3 de la tarde

Son las 4 y cuarto.

Son las once de las noche.

100 is written cien when it is just a number.

When used a an advertb on quantity it can be written as:

Cien carros (one hundred cars)

Cien por ciento (100 percent)

Answer 2

Es la is used when it is one o clock ( because one is singular). Son las is used the rest of the time(because any number above one is plural)
