Answer:here
Step-by-step explanation:
Ok im not quite sure what you mean but I guess you just have to go right 5 1/2 steps and then go down 2 3/4. You start from the "center" of the grid (I don't know what it's called in english..it's not my native language)
17s-10+3(2s+1)
17s-10+6s+3
23s-7
Multiply the top and bottom.
1/2 * 1/2 = 1/4
