The question is which figure shows ∠ POQ.
The answer is the option A.
Justification:
The notation ∠ POQ means angle POQ. And that means:
1) the vertex of the angle is the point O (this is the letter at the center of the name).
2) The sense of the measure is from P to Q counter clockwise.
That is what the figure A shows.
The figue B shows ∠ OQP, the figure C shows ∠QPR, and the figure D shows ∠QRP
Forget about the negative sign. First you have to find a least common denominator. This would be 63. Since we had to multiply 9 by 7 to get 63 we have to multiply the numerator (4) by 7. This gives us a new fraction of 36/63. Since we ha e to multiply 21 by 3 to get 63 we have to multiply 19 by 3. This gives us 57. So now we have 36/63 and 57/63. Then we add the negative sign back in making 57/63 -57/63. Now we add them together. Because one has a negative sign and one is positive the number has to be closer to zero. So the answer is -21/63.
