Question

48:11=. (Ост. ) 74:6=. (Ост. )

Answer 1

48:11=4(ост.4)

74:6=12(ост.2)

Answer 2

I'm not sure what you mean by "(Ост.)", but assuming you are asking to find the quotient and remainder of the following divisions:

48 divided by 11:

The quotient is 4 and the remainder is 4. Therefore:

48 divided by 11 equals 4 with a remainder of 4, or simply expressed as 4 4/11.

74 divided by 6:

The quotient is 12 and the remainder is 2. Therefore:

74 divided by 6 equals 12 with a remainder of 2, or simply expressed as 12 2/6 (which can be simplified to 12 1/3).
