Answers
Given : line ab. 12 centimetres long.
c on it such that ac is 2/3 of ab.
d such that ad is 1/4 of ac
To Find : what fraction of ab is ad?
Solution:
ab = 12 cm
ac = (2/3) ab
=> ac = (2/3) 12
=> ac = 8
ad = (1/4)ac
=> ad = (1/4)8
=> ad = 2
=> ad = 2 * 6 / 6
=> ad = 12 / 6
=> ad = ab/6
=> ad = (1/6) ab
Step 1 : Draw a line ab = 12 cm
Step 2 : Draw an acute angle at A on ab
Step 3 : Stating from A using suitable compass width take 3 point one by one .
Step 4 : join 3rd point with b
Step 5 : draw a line parallel to line drawn in previous step passing through 2 nd point and intersecting ab at c
ac = (2/3) ab
Use same procedure ac = (1/4) ad
ad is (1/6) of ab
