Yes, fractions are fine

For question 13, the one regarding the equation of the line parallel to line L, would I still get all 5 marks for saying the equation of the line was 75x - 100y = 475 instead of simplifying it as all a, b and c are integers as the question asks.

Question 22 was 188 cm^2
Question 21 was 25/84
The Pythagorus in 3-D was 24.3 degrees.
The circle theorem question was 63 degrees.

If you put 63 as answer you'll get the marks, it was 48 and then you had to add it to 15 so 63 total

oh crap. whats an A

May I add that the solution to the equation 2x^2 - x - 120 = 0 is that x = 8, not x = -7.5 as it is length so it cannot be negative.

the one to do with k
k<2.5
The largest whole number that k could be was 2

The 5 mark question on rupees:
52% (It's 51.6 then you had to round it to the closest whole number)
