For example 4.31 = 4.3
0.089 - 1.135 =	Choose the most appropriate option:
A) 1.05 B) 1.04 C) - 1.05 D) - 1.0 E) - 0.1

Rationale: here let the first quantity be a = > a rounded to nearest tenths = > 0.1 similarly let the second quantity be b = > b rounded to nearest tenths = > 1.1 = > a - b = 0.1 - 1.1 = - 1 hence a - b = - 1 answer : d
Answer: D
