Answer 2

`3 (11)/(27) \\`

Explanation:

`(2a - (1)/(3) ) / (b)/(15) \\ (2 * - (3)/(5) - (1)/(3) ) / ( - 6.75)/(15) \\ ( - (6)/(5) - (1)/(3) ) / ( - 6.75)/(15) \\ ( - (6 * 3)/(5 * 3) - (1 * 5)/(3 * 5) ) / ( - 6.75)/(15) \\ ( ( - 18 - 5)/(15) ) / ( - 6.75)/(15) \\ - (23)/(15) / ( - 6.75)/(15) \\ - (23)/(15) * - (15)/(6.75) \\ (23)/(6.75) \\ (23 * 100)/(6.75 * 100) \\ (2300)/(675) = 3 (11)/(27) \\`
