The average is found by adding the numbers and dividing by 2.
Since the average is 17, the total of the two numbers must equal 17 x 2 = 34.
One number is given as 11, so subtract 11 from 34:
34 - 11 = 23
The other number is 23.
Too check: add 11 and 23 and then divide by 2:
11 + 23 = 34
34/2 = 17.

-1/8 - 55/8 = -56/8 = -7
3.4
(-4x7)/10 = -28/10 = -14/5
3.5
-19/2 ÷ 38/7 <=> -19/2 x 7/38 and simplify = -7/4
9 3/7 would be your answer

Step-by-step explanation:
12/4
The top number always goes inside (larger or not), and the bottom number always goes on the outside (larger or not).
______
4 | 12
Ask yourself how many 4's are in 12.
Let's see one 4 is just 4.
We can probably do more 4's than that.
Two 4's gives us 4+4=8.
Let's see if we can put one 4 in there.
Three 4's gives us 4+4+4=12.
So we can fit three 4's into 12 and there is nothing left over.

______
4 | 12
-12 (since 4 times 3 or 4+4+4 is 12)
