So something like segment AB will get shorter.

Calculator display for = 0.75
calculator display for = 0.41667
Calculator display for = 0.5833
Step-by-step explanation:
Calculator display for is 0.75
Yes , it is the exact decimal equivalent.
= 0.75
9 ÷ 12
=3 ÷ 4
= (3 × 25) ÷( 4 × 25)
= 75 ÷ 100
= 0.75
calculator display for = 0.41667
= 0.41667
It is not the exact decimal equivalent.
5 ÷ 12 = (5 × 8.35) ÷ ( 12 × 8.35)
= 41.75 ÷ 100.2
= 0.41667
Calculator display for = 0.5833
It is not the exact decimal equivalent.
7 ÷ 12 = ( 7 × 8.35) ÷ ( 12 × 8.35)
= 58.45 ÷ 100.2
= 0.5833
