Answer 3

To solve the expression 1 23/45 : (3 2/5 - 1 2/15), we need to simplify the components within the parentheses first and then perform the division.

Step 1: Simplifying within the parentheses 3 2/5 - 1 2/15 = (3 + 2/5) - (1 + 2/15) = (15/5 + 2/5) - (15/15 + 2/15) = 17/5 - 17/15 = (173)/(53) - (171)/(151) = 51/15 - 17/15 = 34/15

Step 2: Division 1 23/45 : 34/15 = (45/45 + 23/45) : (34/15) = 68/45 : 34/15 = (68/45) * (15/34) = (6815) / (4534) = 1020 / 1530 = 2/3

Therefore, 1 23/45 : (3 2/5 - 1 2/15) simplifies to 2/3.
