Answer:
A 12.9
B 13.4
C 11.8
Step-by-step explanation:
From 12 to 13, there are 10 small segments.
From 12 to 13, it is 1 unit.
That means that each small segment is 1 divided by 10 units long. Each of the small segments is a tenth of a unit, or 1/10 of a unit, or 0.1 unit.
A
12 + 0.9 = 12.9
Letter A is 9 tenths more than 12, so A corresponds to 12.9
B
12 + 0.4 = 12.4
B is 4 tenths more than 13, so B corresponds to 13.4
C
12 - 0.2 = 11.8
C is 2 tenths less than 12, so C corresponds to 11.8
