Question

Instead of multiplying by 1/2 ,1/3 and 1/4 , we shall multiply by 180°/360°,120°/360° and 90°/360° respectively. Why ?​

Answer 1

Step-by-step explanation:

this is because,

180/360=1/2 upon simplifying

120/360=1/3 upon simplifying

90/360=1/4 upon simplifying

thus, writing 1/2, 1/3 and 1/4 as 180/360, 120/360 and 90/360 is the same thing.
