Answer: 1 7/16
Step-by-step explanation: If you look at a ruler 1 7/8 is just a little behind 1 7/16 while 1 3/4 is far behind. Also 2 1/8 is past where the green line stops.
Answer:
option 1) 1 7/8"
Step-by-step explanation:
its clearly visible that the green line covers 1 unit completely.
but it stops before it can reach 2 units.
check the attachment
it will be at a distance of 1/ 2 units from the "unit 1".
( since 1 and 2 are 1 unit apart their mid point will lie exactly at rhe center that is 1/ 2 = 0.5)
since the "mid point" is at a distance of 0.5 units from "unit 2", second mid point will be at a distance of (1/ 2)/ 2 = 1/ 4 units from "mid point".
since they're 1/ 4 units apart the third mid point will be (1/ 4)/2 units away from "second mid point"
and this is where the green line stops!
we got these points now well just add them up, to get the distance of required point from unit 1.
1/ 2 + 1/ 4 + 1/ 8
= 7/ 8
and this is in centimeters so add a " after it
1 7/ 8"
that is option 1.
