The 0 is needed as a placeholder between the decimal point and the hundredths' digit. For numbers between 0.1 and 0.2, there is a 1 in the tenths' place: 0.11, 0.12, 0.13, and so on. For numbers between 0.2 and 0.3, there is a 2 in the tenths' place: 0.21, 0.22, 0.23, and so forth.
The midpoint of 0.1 and 0.2 is 0.15.
What is the midpoint?
The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.
To find the midpoint we just have to add both the numbers and then divide by 2.
So, midpoint be,
= (0.1+0.2)/2
=0.3/2
=0.15
Thus the midpoint of 0.1 and 0.2 is 0.15.
