"Bylo jich devět?"

Translation: Were there nine of them?

[mattvick]

Could “it was nine of them?” Also Ben accepted?

[chris95041]

In English, that would be grammatically incorrect. The plural form 'there were' is needed to agree in number with 'nine'.

[Willem_vd_Hel]

Were they with nine, is not accepted. Why?

[VladaFu]

It means something else.

[horsthartm2]

"Where there nine?" Of them is obvious! Thx

[horsthartm2]

"There were nine (of them)." also possible, if it's a listening task.
