Answer 2

Let's break down each part of the expression and solve step by step:

1. $16 \frac{3}{25} - 4 \frac{9}{10}$

   To subtract mixed numbers, subtract the whole numbers separately and then subtract the fractions.

   $16 - 4 = 12$

   $\frac{3}{25} - \frac{9}{10}$

   To subtract fractions, find a common denominator (in this case, 50) and then subtract the numerators:

   $\frac{3 \times 2}{25 \times 2} - \frac{9 \times 5}{10 \times 5} = \frac{6}{50} - \frac{45}{50} = -\frac{39}{50}$

   So, $16 \frac{3}{25} - 4 \frac{9}{10} = 12 - \frac{39}{50}$

2. $41 \frac{9}{10} \times 5$

   Multiply the whole number by 5 and then multiply the fraction by 5:

   $41 \times 5 + \frac{9}{10} \times 5 = 205 + \frac{45}{10} = 205 + 4.5 = 209.5$

3. $3/5(3 + \frac{15}{9} ÷ 3 \frac{1}{2}) + \frac{186}{3} ÷ 6$

   Let's break this down step by step:

   $3 + \frac{15}{9} ÷ 3 \frac{1}{2}$

   First, simplify the fraction:

   $\frac{15}{9} = \frac{5}{3}$

   Now, divide by $3 \frac{1}{2}$:

   $\frac{5}{3} ÷ \frac{7}{2} = \frac{5}{3} \times \frac{2}{7} = \frac{10}{21}$

   Now multiply by $3/5$:

   $3/5 \times (\frac{10}{21} + 3) = \frac{3}{5} \times \frac{31}{21} = \frac{93}{35}$

   Next, $\frac{186}{3} ÷ 6 = \frac{62}{6} = 10$

   Finally, add the two results:

   $\frac{93}{35} + 10 = \frac{93}{35} + \frac{350}{35} = \frac{443}{35} = 12.657$

So, the overall result is:

$12 - \frac{39}{50} + 209.5 + 12.657 = 234.157 - \frac{39}{50}$
