Answer:
Option C
Step-by-step explanation:

The remainder being 2 is not divisible by 4, we introduce a decimal and trailing zero. 20÷4=5 hence the answer of 10÷4 will be 2.5 because it had a remainder and we introduced a trailing zero.

If the first integer is x, the second integer must be (x+1) since you know they are consecutive. So you can write:
x+(x+1)=57
2x+1=57
2x=56
x = 28 and x+1=29
28+29=57.
