Marking points
M1 (a) · 1 mark · Convert all fractions to common denominator or decimal
A1 (a) · 1 mark · Correctly order fractions: 5/12 < 2/3 < 3/4
B1 (b) · 1 mark · Correct coordinates for reflection: (2, -3)
A2 (c) · 1 mark · Correct numerator 8 for denominator 12
Worked solution
a) , , . So order is 5/12 < 2/3 < 3/4.
b) To reflect (2, 3) across x-axis, change sign of y-coordinate: (2, -3).
c) . So numerator is 8.
