Answer 3

To solve the given expression step by step, we'll first work on the addition and subtraction within the parentheses, and then perform the multiplication and division according to the given order of operations:

Step 1: Simplify the expression within the parentheses $1 \frac{23}{45} + 16 \frac{7}{20} - 6 \frac{1}{15} + 0.65$

Convert mixed fractions to improper fractions: $= \left(1 + \frac{23}{45}\right) + \left(16 + \frac{7}{20}\right) - \left(6 + \frac{1}{15}\right) + 0.65$

$= \frac{45}{45} + \frac{23}{45} + \frac{320}{20} + \frac{7}{20} - \frac{91}{15} + 0.65$

$= \frac{45 + 23}{45} + \frac{320 + 7}{20} - \frac{91}{15} + 0.65$

$= \frac{68}{45} + \frac{327}{20} - \frac{91}{15} + 0.65$

Step 2: Perform the operations $= \frac{68}{45} + \frac{6540}{20} - \frac{2730}{45} + \frac{585}{45}$

$= \frac{68}{45} + \frac{327}{45} - \frac{2730}{45} + \frac{585}{45}$

$= \frac{68 + 327 - 2730 + 585}{45}$

$= \frac{-1750}{45}$

Step 3: Perform the multiplication and division $\left(\frac{-1750}{45}\right) \times \frac{1}{3}$

$= \frac{-1750 \times 1}{45 \times 3}$

$= \frac{-1750}{135}$

Step 4: Simplify the fraction $= -\frac{350}{27}$
