Let's simplify the expression step by step:
Since the original expression involves division by 0.4, the final result is 1.0101010101... / 0.4 = 2.52525252525... (repeating decimal).
Let's simplify the expression step by step:
2 × 2 = 43 × 3 = 98 - 0.12 = 7.887.88 × 1/2 = 3.94(4 / 3) / 3.94 = 1.0101010101...Since the original expression involves division by 0.4, the final result is 1.0101010101... / 0.4 = 2.52525252525... (repeating decimal).
