2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3. Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.
The angle inside the triangle by the 53 is also 53. We know triangles have 180 degrees so the other angle is 180-53-60=67 X is the supplementary angle to the 67 so x=113
