Question

Miko was facing north-west at first. She turned in an anti-clockwise direction and faced north-east. What fraction of a complete turn did she make?

Answer 1

3/4

Explanation:

NW is 45° counterclockwise (anticlockwise) to North

If she turns 45° anticlockwise she will be facing directly west

If she turns another 180° anti clockwise, she will be facing east

To fact NE she must turn another 45°anticlockwise

Total anti-clockwise turn in degrees = 45 + 180 + 45 = 270°

One complete turn is 360°

So the total turn Miko made as a fraction of a complete turn
= 270/360

= 3/4
